My boyfriend and I, both 18, are very comfortable with each other. We took things slow, somewhat due to my discomfort in the religious section and partly to make it more genuine. Skip forward a bit and we are delving into the world of sexual activity. I want to steer clear of PIV sex for pregnancy reasons and virginity reasons....

I am 23, almost 24 years old now, but when I was in 7th and 8th grade and even in 9th grade; when my schools talked about sex education, I learned that a man’s penis size is not set in stone; and will more than likely continue growing until about age 20 or so, sometimes earlier and sometime later....

I don't mean to ask a silly question, but is there anything that makes being female good in terms of sex? It seems to me men have all the biological luck - they are aroused more easily, they orgasm more frequently, they can orgasm regularly from both oral/manipulative sex and intercourse, their is more square inches of erectile tissue to play around with, etc....

I'm a 32 year old woman being driven up the wall by my fiance always telling me he can tell I'm playing with my toys when he's at work because I'm loose that day. I swear to him up and down that I haven't and even tell him the last time that I have done something like that. But he doesn't want to hear it. He always says I'm lying about it all. Why somedays is my vagina tighter than another day?...
