I've only recently become interested in anal sex and even that is only mild because I just can't get past my aversion to the whole poop issue.... but

having said that, the 'doggie style' position of vaginal intercourse has been my favourite with my wife cause its the one that most easily lets me imagine I'm with a boy.

In trying to avoid surrogacy, I'm avoiding that position. I agree that I don't think I could do it and NOT think about a boy.
