Yea, stop the porn watching biz. There really shouldn't be a need to rub one out if like you said "she's pounding and sucking" you all the time. I'm not saying you have to completely stop watching porn every now and again, But I think The_Jazz is right to say that you are more then likely squeezing to hard. Also increasing your stamina by whackin it so much will stop you from cumming so quickly. To add a question to this. You did not specify on how long it takes you to cum (during intercourse). Are you going for hours and hours with no result? or are you fucking for 20-30 min and just getting impatient? Oh, before I go, Might I add that usually you get off to porn quicker due to the fact your fantasizing (dur). Most men I have talked to about this, have roughly the same issue. When explained why they cum so fast watching porn. They tell me it's because A: Its not them B: It feels wrong (But sooo good) as they say. and C: IT'S FUCKING HOT! I would assume a mixture of all for you? yea? Anyway, stop fwap fwapping it to porn and just let your cock have a few days off.
