And what about the male orgasme?? Is that a sin too??

The fact that only 1 out of 3 women gets an orgasm is not because they are whores, perverts,... it's just because female body is much more diverse than a male body. Some women are just less sensitive than others and need more stimulation (this is where some men fail and leaves the women unsatisfied). Why shouldn't women enjoy sex with their husband/friend??
