Basically the title.

Been banging this chick for a couple months now, but ever since the first time, I come too quickly and have to wait like 10 minutes before I can go back at it, time during which I usually eat her out, but its just embarrassing, and, after discovering the RP and the importance of dominance in the bedroom, I feel like my body is just betraying me.

Thought I'd ask here for advice from guys with more experience. Also, for the record, im 18, and the chick on question is the one I lost my V-card to (if that has anything to do with it).
