I'm 13 and my boyfriend is 16. I'm a virgin but he isn't and I feel like if I don't have sex with him he is going to break up with me. Should we just have oral? Also, how can you tell if someone has already had sex?

Due to moral and possibly religious reasons, I want to wait 'til I am married before I have sex. But as a woman, I am worried that many men will not wait for this length of time and also will not be virgins by the point of marriage.

I made a big fashion faux pas today to wear leggings without anything to cover my butt/crotch which resulted in a "cameltoe" (slang for labia majora being outlined through tight clothes). And a guy at school rudely pointed it out to me and implied I must have a lot of sex because that makes the outer lips more fleshy and prominent.

The thing is, I haven't had any sex, I'm still a virgin, so I was pretty embarrassed and offended. I just thought cameltoe was caused by clingy, tight clothes. Was this guy just ignorant about girls' bodies or is there some truth to what he is saying? I honestly feel ridiculous asking but I just had to make sure.

I'm a Christian, and I have decided to save myself till marriage. I'm perfectly fine with that. My boyfriend is fine with that too (we've been together a month), and respects my decision. However, like any celibate person would admit, sometimes I get these truly surreal urges for sex: I catch myself thinking that maybe even a little bit of touching while kissing would be fine, or I just think about what it would be like if we ever got married and ended up sleeping together. I have said nothing to my boyfriend, in case he misconstrues it as an invitation, but it has recently been very, very difficult to resist, especially with all these hormones making me want sex. I want to stay true to my decision to stay premaritally celibate, and I will pride myself on not being tempted, however my urges make the battle all the harder sometimes. Any suggestions?
