So, making out with this chick last night, going at it pretty good, heavy petting and all....I'm on top of her, we're both still fully clothed, and she keeps grinding with her hips....And I don't know what the deal was, maybe I was just having too good a time or she was grinding just right, but I came right there! what the hell? Damn, that's embarrasing...no handjob/blowjob for me tonight. Other times I've lasted forever....I can usually get a girl to come at least once, sometimes twice or even three times before I'm spent. I just don't get it.
