I used to think great face, but now body - I have fucked some fat gal's who really didn't turn me on very much, although they had a nice personality and were pretty. I was not intensely turned on except with one of them and that's coz she was a rampant beast in the sack, and gave the best head I have yet to experience.
Definitely compromise on having a woman with a not so great (but not ugly - NEVER ugly) boat, and a slamming body - in fact come to think of it the past 3 years this is what I have gone for - my polish lady i been staying with the past week her body is great even though she's had 2 kids, and her face is seriously pretty half the time, and kinda stereotype-witchy a smaller half; and the woman I was seeing for a while before her, had a nice slim curvy body - perfect body, she was short and had a pretty face, which was not amazingly attractive when she got drunk, which was fairly often.
Sexually arousing body > face anyday.
