So I'm almost 17 and I've only done anything physical with three guys in my life, with whom all I had been in a relationship with. I have a friend (pretty attractive) who has asked to hook up tomorrow night. I said I would, but there's still time to back out. I'm really nervous because I've never hooked up with anyone before, and I'm not so sure what to do. What are your opinions on hookups? Pros and cons? Past experiences? Any kind of feedback and advice of that sort would be greatly appreciated! :)
