Most casual dating websites measure success in matches per minute. We measure it in genuinely good nights. NotAboutSize is built for adults who want unhurried, anatomy-aware intimacy — partners who already know that fit, rhythm, and presence matter more than inches.

Sex doesn’t have to hurt to count. Across casual dating websites the standard pitch is variety and speed; here, the pitch is fit. Three benefits show up again and again in member feedback when partners stop chasing average and start chasing comfort.
For partners with sensitivity, smaller dimensions mean penetration that feels good from the first thrust instead of needing twenty minutes of warm-up. Less soreness afterward, fewer interrupted sessions, more nights worth repeating.
Smaller anatomy makes oral sex more comfortable for the giver, hand play more precise, and the whole rhythm of foreplay less performative. Partners report longer, more relaxed sessions and a wider range of acts on the menu.
When neither partner is white-knuckling through size anxiety, attention shifts to the things that actually drive satisfaction: eye contact, breath, tempo, sounds, the bits in between. Casual doesn’t have to mean disconnected.
For a meaningful share of adults, comfort isn’t a preference — it’s a medical reality. We built the category so those members don’t have to over-explain on a first date.
Vaginismus is the uncontrollable tensing or contracting of the muscles around the vaginal opening in response to attempted penetration. It can show up during sex, tampon insertion, or pelvic exams, and it’s often described as a feeling of hitting a wall. The DSM-5 groups it with dyspareunia under genito-pelvic pain/penetration disorder (GPPPD). Per the Cleveland Clinic Health Library (last updated July 2025), it’s very treatable — but it doesn’t resolve on its own and it’s far more common than most people realize.
Vaginismus is not the only condition that benefits from anatomy-aware partners. Endometriosis, pelvic floor dysfunction, cervical sensitivity, vulvodynia, post-menopausal tissue changes, and recent recovery from childbirth or surgery can all make larger penetration uncomfortable or actively painful. In each of these contexts a smaller penis isn’t a compromise — it’s often the configuration that makes the difference between sex that hurts and sex that feels good.
That’s the gap our category exists to close. Mainstream casual dating apps don’t hold space for any of this. Members tell us they’ve declined dates for years because they didn’t want to spend the first 20 minutes of meeting someone explaining a pelvic condition. Here, the explaining is already done. Profiles include optional fields for pace preference, sensitivity notes, and lubricant friendliness — small details that reset expectations before the first message.
You don’t need a diagnosis to want gentler sex. Plenty of members are simply tired of casual dating websites that confuse intensity with quality. Slow is allowed. Light is allowed. The whole point of a niche space is that nobody has to defend their own definition of good sex against someone else’s.
The cultural script around size is loud. The evidence is not. Here’s a tight summary of what peer-reviewed work and survey data actually report.
The outer third of the vaginal canal contains the highest concentration of nerve endings. A wider circumference creates more contact and friction in that sensitive zone; extra length past a certain point adds little sensation and can be uncomfortable when it meets the cervix. That’s why girth ranks higher than length in nearly every study that asks women directly — PLOS ONE’s 3D-printed model research, the 2001 BMC Women’s Health survey, and UCLA’s direct-ask survey all converge on the same finding.
And because penetration isn’t the primary driver of orgasm for most women, the most impactful skills a partner can develop don’t depend on dimensions at all. Clitoral attention, oral technique, manual play, rhythm, communication, breath: every one of these scales with practice and presence, not anatomy.
Confidence is the single most-cited trait women describe as sexy — not bravado, but the calm of a partner who knows what they’re doing and isn’t apologizing for their body the entire time.
Confidence drives sexual satisfaction for both partners. Men who feel good about their bodies are more present, more communicative, and more attentive during sex — and that reliably matters more than a fraction of an inch. — Synthesized from research on body image and sexual satisfaction
Across thousands of intimate-survey responses, the same handful of partner behaviors keep ranking at the top of what makes sex good. None of them are anatomical:
Confidence is the soil all of these grow in. That’s why this category exists alongside our other spaces — spending time in a body-positive room makes confidence easier to keep. For deeper reading, see building body confidence as a man.
Some positions are dimension-agnostic. Others actively flatter smaller anatomy by changing the angle of entry, the depth of contact, or the friction profile. Here are three from our full guide.
The receiving partner controls depth, angle, and pace from on top. A slight forward lean shifts contact toward the front wall — the most nerve-rich area — and lets clitoral grinding happen against the giving partner’s pelvis at the same time.
See full descriptionThe receiving partner lies face-down with a pillow under the hips. The angle creates a tighter, snugger fit and gives the giving partner full access to the neck, shoulders, and lower back for kissing and touch throughout.
See full descriptionBoth partners lie on their sides at a slight diagonal. Easier on hips and knees, allows long sessions without fatigue, and the angle naturally favors girth-forward contact over length-driven thrusting.

Most casual dating apps are built on volume. That works fine until you have a specific need — like a partner who already understands comfort-led intimacy. Here’s how a niche space compares with a mainstream one.

Yes — casual dating is a recognized relationship style where adults pursue dates, intimacy, or short-term connection without expecting marriage or cohabitation. On NotAboutSize the casual lane sits alongside long-term and friends-with-benefits options, and members declare their intent on their profile so nobody guesses. Roughly 35% of U.S. dating-app users describe their current dating as casual (Pew Research Center, 2023).
The 7 7 7 rule is a casual dating guideline that suggests planning a date every 7 days, taking a longer 7-hour date roughly every 7 weeks, and going on a weekend-long trip together every 7 months. It’s not a hard rule — it’s a rhythm framework for keeping a casual or open relationship feeling intentional without overcommitting.
Yes — this category was built with sensitivity-aware partners specifically in mind. Optional profile fields let you signal pace preference, lubricant friendliness, and any positions or acts you’d like to skip, so matches arrive already on the same page. None of these fields are visible by default; you choose what to share.
For many partners, yes. Conditions like vaginismus, endometriosis, pelvic floor dysfunction, cervical sensitivity, and post-menopausal tissue changes can make larger penetration uncomfortable or painful. A smaller penis often allows sex to feel good from the first thrust instead of requiring extensive warm-up. Comfort isn’t a compromise — for these partners it’s the configuration that makes good sex possible.
Most fwb sites optimize for speed and volume. NotAboutSize’s sex category optimizes for fit — specifically anatomy-aware fit. Profile fields include pace, sensitivity notes, and aftercare preferences; the tone is plain-language rather than crude; and the member base has self-selected for comfort-first intimacy. You can still keep things casual; the difference is that casual doesn’t have to mean rough or rushed.
Across multiple studies, women consistently rate thickness as more important than length for physical satisfaction. UCLA’s direct-ask survey found over 85% reported girth was more critical to satisfaction than length. The anatomical reason is simple: nerve endings concentrate in the outer third of the vaginal canal, so circumference creates more contact in the most sensitive zone.
