Okay, here's my deal. Back when she would do that kind of thing, my girlfriend gave me head for about thirty-forty minutes. Thing is, she would only do it that long because that was when her jaw and tongue would get tired, and I hadn't cum yet. She's stopped giving me BJs because she doesn't see any point in it. Is it possible for me to train myself to cum faster? Side note: For some reason, I cum within five minutes when she jacks me off. Weird? Typical?
