Have you had sex before? I felt that way until I had sex. I was just kinda afraid of the intrusive nature of it, but like you, I wanted to try it. It was actually all my girlfriend at the time's doing. She instigated and planed the night. If she wasnt the move maker i'd probably never had made a move. But after that night, couldnt get enough =P.
I kinda felt something then that i didnt realize till years later, the difference between making love and sex. It sounds like you've had multiple suitors, given the statement 'many guys.' So probably not a whole lot of love between you and the guys, so hold off till you find it. There is nothing at all wrong with holding off till you love someone. And not even love, but someone you care about. Making love is about opening up yourself at it's most vulnerable state to one-another knowing and trusting that both your intentions are to make the other feel as good as possible (where as 'sex' can be just "take off your clothes, i want an orgasm").
So, basically, yes, it's ok to be hesitant, think about it, as a women, you're allowing someone inside of you (and you guys, should realize more and respect what it can mean to a women to physically allow someone inside them). And with the nature of AS to be opposed to physical contact the idea of not just touching you, but being inside you is obviously very off putting.
You dont have to wait out some fabled true love, but wait till you at least find someone with mutual feelings and care for one another and do it. You will be pleasently surprised, then you can move on to all the fun and kinky stuff involved in sex once you feel comfortable with each other
