Opinions please!!!!!

Hey ladies I really need your help with this one. So I recently got in touch with an old friend from high school and I haven't seen him in about two years. I had a serious crush on him while we were in school and he knew it too. He wanted to be my first but I told him no I wasn't ready. He hmu about a couple of weeks ago and we started hanging out again. He's the only guy I actually feel comfortable hanging out with. I'm still a virgin and he was actually surprised when I told him. he just wants to be friends with benefits but frankly I want to be in a relationship with him. He knows i want he badly. He's actually the only guy i can imagine doing anything with right now. I want him to be my first and he keeps asking to be, but I want to be his girlfriend not his sideline. I'm really an independent person, I've never really wanted to do the whole dating thing or be in a relationship. but when it comes to him thing are different when we hang out it gets very intense. Even my best friends have noticed a diffrence in my behavior. I'm having a really hard time figuring out what to do with him. Your opinions would be very helpful please...
