I'm 19 and my boyfriend is 28. We've been having sex for a year now and we have not been very careful at all. We never use condoms! It's weird though cause I have not gotten pregnant. He usually doesn't ejaculate in me LOL but still. . . . I always joke and tell him he's sterile but now I'm really thinking he is. Since I haven't gotten pregnant does this mean there is something wrong with my boyfriend or me? Or does it just mean I'm lucky?

I feel like at my age (16), it is so young to have sex. If I were to be dating someone right now, so many things would scare me, that I would choose not to have sex. The chance of an STI, pregnancy, not being good enough for my partner, having my parents find out, and so many more things. I'm scared that during sex, that I wont know what to do and I'm just not comfortable with my body. Most of my friends are having sex and they say they like it, but the fact is, that I'm terrified. Everything about sex scares me. I'm worried about my body, what my partner will tell his friends, the rumors that will get around school, being inexperienced, and I'm scared it will hurt for the first time. I don't want to be seen as up tight for not wanting to have sex, and I know I don't mind having sex before marriage, but I was just wondering about moving past my fears and letting go. So, if you have any ideas, I would love to hear back from you.

I'm 17,and I have been dating this guy for like a year. We just started having sex, and the other day we were going to but he wanted me to give him head before so he would last longer...then he could not get it back up. He tried hard to but it just wouldn't. Was it me? Can I just not do it for him or something?
