Long time lurker, first time poster. Hopefully this is somewhat simple, but my SO and I can't seem to find a simple solution. We've been in a committed relationship for almost 6 years now, and having regular sex for...4, maybe 5 years now. As we've both become more comfortable and experienced, we've recently come across a problem... When we first started out, everything was great, no real problems, but recently (less than a year) I've been lasting longer (yay!) but that's part of the problem. We use lube (astroglide) and we don't rush anything, great foreplay, etc. But it's becoming very tough for her to keep up, lately she's been stating that she gets very sore, and sex becomes VERY painful for her. It doesn't seem to be muscles, or lack of being fit, but I haven't been able to get more than halfway there before she's yelling for me to stop... As I mentioned, we use plenty of good, old astroglide, we don't rush anything - we're both quite ready before we get into it - but we're consistently running into this same problem. We stopped using condom's roughly a year and a half ago, that didn't seem to cause any problems, though we started using a spermicidal contraceptive at the same time, on top of her birth control pills. The only thing that stands out in my mind is the spermicidal contraceptive, or the fact that she has recently changed birth control a couple months ago (though she had been on the same for quite some time beforehand - and this issue was happening before as well). If any of you wonderful sexperts have a suggestion, or something we should look into, I'd appreciate the help greatly! Thanks in advance!
