sex and virginity

I'm a virgin and I have an option to not be one. I've been thinking about it and I want to do it but I keep thinking about how I don't want it from that specific person but I want to try it and no one else is offering. I'm comfortable with this person and he's been a friend of mine for years but he has a lot of girl and I don't want to be one of those girls. I'm not saying that I want to be his girl I just want to lose it to one person I have in mind but I don't know if he's going to be coming back into my life
