I read that it takes 7-9min of clitoral stimulation (depending on the girl) to make a girl cum. What is the average time for you guys/girls? I've done the shit for what seems like forever. I always end up stopping before she cums because my tounge gets cut(on my teeth) or hurts really bad. So, either it takes her longer, I haven't gone that long, or I just really suck at it. Anyway, how long should it take.
