I'm sorry, but it is neither natural nor healthy to have to have sex in the same exact pose every single time. Humans evolved to have sex face-to-face, so having sex doggy style is about as "unnatural" as you can get.*
As a woman, I cannot stimulate my clitoris if I am on my stomach and a male is on top of me. That means I get NO PLEASURE from sex and yes, you might as well be raping me. I could go read a book while you do your thing. In fact, why don't you just hump the bed? I'll go play WoW, kthnxbai.
DMA_XP, I would NEVER date a boy as callous and inconsiderate as you. You clearly know nothing about how a woman receives pleasure during sex.
Moving on... Circumcision does more harm than good. The male loses more than 50% of his sensitivity, and his movements during sex are completely different. A circed man will thrust deep, long, and hard. This is NOT pleasurable for a woman, no matter what porn videos say. Women need quick, shallow, gentle stimulation and this is how an un-circed man has sex.
It is indeed possible that circumcising a baby could in fact lead to TMS, as the child does not have the normal sheathe of skin to masturbate with. Circumcision as a religious issue should only be done if the parents are religious.
