I'm closing in on 18 and I've been in a relationship with a girl for a few months. We've had some fun with a little foreplay, going down on each other, mutual masturbation, everything minus sex toys and actual sex. Thing is, I'm really good at fingering her, and I can get two to three actual real orgasms out of her....
This is going to sound stupid but I have a question and its simply this: how do you know when you've orgasmed? I had my first time to other night with a guy I love very much but when he asked me if I came I didn't know. I have no experience at sex at all....
