<human>: Throwaway obviously. I was going to post this to /r/sexadvice, but I think it might be better here. I'm 26 and am currently in a long distance relationship until I finish college in the spring. 

We've known each other online for years now, and he is coming to visit for the first time in a month for a week. 

The problem is that I suffer from primary tokophobia, which is a deep fear of pregnancy and childbirth. He is aware of this, but I don't think he comprehends how bad it is.

The fear comes from a mix of childhood sexual abuse (non-familial) and helping my mother deliver my brother on the bathroom floor when I was 4. While I can tolerate children, infants and pregnant women terrify me. 

Also the even idea of having intercourse sends me running. One example: when I was 19, I attempted to have a one-night stand. Things were getting hot and heavy but just as he was rubbing himself against me I freaked out and ran away. Never saw him again-- poor thing.

Since that incident, I dated women. I thoroughly enjoy having sex with women, but I have never met a women I had much in common with (I'm very geeky.). 

Anyway, I have decided to take this leap and try to attempt a serious relationship with a guy for the first time. He knows about my fears; he knows I never want children; he knows I have very limited experience with men. 

So far, our relationship has been perfect for me despite not being in each other physical presence, but I know he is beyond ready to move it to the next level.

Right now I'm unemployed and can't afford a permanent (or temporary for that matter) solution to avoid pregnancy.

**My question is: do you think its fair for me to ask him to hold off on sex for at least this visit?

Can you give me the gist of the text in a nutshell?
<bot>: My long distance boyfriend is coming to visit, and I don't know how to say I don't want to have sex.
