ok so I have this guy friend, who I wasn't really attracted to until like last week for some reason,anyway i was hanging out at his place after a night out the other night and one thing led to another and I ended up giving him oral. After about 2 or 3 minutes I stopped because I felt awkward,and when he asked me to finish I refused. He gave me a frustrated sigh and left out the room.

Every since that night I have been thinking about him sexually. I've been having dreams about having sex with him,and wishing that I would of when a little bit further that night. As you all know I'm a virgin,so I highly doubt if I would of did that night all over that I would of gave it up to him,but then again I might have. It's just weird. I had class with him today and at first I couldn't even look at him,but I didn't want anybody to think that anything happened between us so I interacted with him as usual and he did the same. But I still felt sick about it. I just don't want to ruin our friendship.

What is going on? Why do I feel this way? Do I really have a crush on him or am I just lusting after him sexually?
