When I use condoms, I can last a lot longer pumping, but still cum pretty fast (2 mins of hard deep pumping in my fav position). Sometimes, especially at the beginning of the session I'll put it in raw for no more than a couple minutes just to let us feel eachother before putting the condom on and really beginning. During this raw time I find in certain positions I can climax from 0-100% in less than 30 seconds. It just feels too good and she's just too tight (she was a virgin 2 months ago). I usually have a rotation while fucking where I'll jackhammer for about 1-2 minutes then go slow or stop completely to rest myself and to not cum before I start again.

Is this normal? Has years of porn caused a problem for me? Any way to de-program myself and last longer in the future?
