wawa, i'm gonna play the DEVIL here... try this: 
whenever he juz take off ur shorts in the morning and juz pump u or
whatever condition that u r not aroused, pick up a cigarette and
smoke while he pump, or read a mag, or watch tv, or file ur
fingernails, or play wif ur handphone while he do all the
pumping.
it wont really piss him off, but he will juz feel funny or puzzled.
after a few times, he will give up doing all the nonsense.
if a girl were to do this to me, i have no mood to fuc*k at
all.
he give u nonsense, u pay him back nonsense.
