I lost my virginity when I was 16 and yes I regret it deeply. He ended up leaving me in the end to find some other girl that he could use to get what he wanted. I'm the same age as you are, I'm 17, but my suggestion is to wait until you know for sure and certain that this is the guy that you want to take your virginity. Waiting to have sex can eliminate possible heartbreak, pregnancy, and STD's. Oh lord I sound like an adult now, all I'm saying to you is to just make sure that this is what you want to do. Please keep me posted and let me know how things turn out for you!
