Q: Does size really matter?
As this question appears on pretty much every sex Q&A column I've ever read, it seems fitting it would be our first query here at Things You Can't Ask Mom. And the answer is, yes, it absolutely does. Of course it does! Men come in all different sizes, right? Well, newsflash folks: so do women. I fail to see where anyone gets off saying "no, size doesn't matter" … unless they're just not very experienced, or they have the vaginal muscle control of an advanced tantric master.
Yes, almost any woman can both give birth and keep a tampon in place inside her vagina, amazingly elastic, versatile things that they are. However, childbirth is not something most women would choose to do recreationally, and tampons are so small as to become unnoticeable to most women within a few seconds after insertion … neither of these extremes is something you want your penis compared to, I'd think.
But here's the deal: there is a great deal of latitude in the size range within which a penis will be perfectly capable of satisfying most women. Bigger is NOT always better. While I do I know one woman who dated a man with a 12" cock and said it was the most wonderful thing she'd ever had, that very same man, years later, dated another female acquaintance, and was physically unable to penetrate her more than half way. I have personally been with men with whom certain otherwise favorite positions were tragically off limits because it felt like they were trying to play billiards with my ovaries: not pleasant at all. Then there are some women who enjoy having their cervix bumped during sex, and other women who are so sensitive they'd rather be with a man who can't penetrate them fully.
In a way, men on the smaller end of the scale are actually the luckier ones. Even a very small man with an open minded partner might find that a combination of toys, anal sex and creative positions more than makes up for less-than-earth-shaking vaginal penetration. In my own experience, a smaller partner can accomplish great things with a combination of stamina and mutual flexibility! (Maybe someone should start couples yoga classes especially for 'petite' men and their partners?) A man who's partner can't fully accommodate him, on the other hand, is pretty much either stuck with never being able to stick it all the way in, or with finding another woman.
So, in short, yes. Size matters. But different sizes matter differently to different women, for different reasons. Looking at my ruler right now, I'm estimating a good 4" range between the lower and upper end of men who had no particular problem getting me off … the lower end involved a bit more acrobatics, and the upper end had to forgo doggie-style, but that still leaves a lot to be done in both cases. I'm wagering the vast majority of men aren't going to have much problem finding a woman who's personal size preferences are a perfect match.
