Dear Sh! Sometimes my boyfriend's penis won't fit inside me. What is wrong?
Is his penis too large?
Your vagina is an amazing organ that is expandable (rather than an open space), so it's unlikely that your boyfriend's penis is too big.
If his penis 'doesn't fit,' your body is probably not aroused, relaxed or wet enough for penetrative sex. A squirt from your trusty lube bottle and lots more lusty loving of the non-penetrative sort will help prime your body to a 'give it to me' state of readiness.
Try not to worry or anticipate failure. This will only cause you anxiety, making your body even tenser. It's a vicious cycle.
Be open with your boyfriend. For the vast majority of men, their woman's pleasure and orgasm are crucial to them.
Perhaps agree together that sex doesn't always have to involve penetration. This may help to ease your worries. Getting out of your head and into your body is imperative. Deep breathing can also help as it relaxes your body more.
If things persist, or you feel the problem is more than a lack of wetness or arousal, you might want to look into Vaginismus.
Vaginismus causes the vaginal muscles to constrict, making intercourse impossible or painful. The good news is that it can be overcome, with the right help.
We hope this helps.
