lol smartarse, i can too
sublime, go to the pharmacy or supermarket and get some nappy/diaper-rash cream (the stuff they use on babies with diaper rash) apply it several times a day and try to give your dick some exposure to air (ie lounge around/sleep naked) and most importantly...dont aggravate it anymore, alright. leave the poor guy alone instead of beating the shit out of him
i could sit here diagnosing exactly what has caused it, but chances are its a multifactorial thing and besides, the solution is going to be the same as what i said above, so stop wasting time and just do it.
if you cant get the cream and its nighttime there, just sleep naked. oh, and dont wash it with soap. just use water.
and yes, washing it for 10 minutes until orgasm counts as playing with yourself. dont do it
