y do i ejaculate premature when im having sex

nothin' ta worry ... practice makes a man perfect !!!

bcuz u have not learn 2 control urself. try slowin down when ur ready 2 come. And just kiss, or switch 2 oral sex. R u using a condom? It will b less sensitive with 1 on. U can buy stuff like MAdelay, numbs Ur penis. Try masturbating and build it up and stop and repeat. Masturbate b4 u r goona have sex.
