I will be the first to admit that I started working out almost entirely for women. I'm not at all ashamed to admit it. Women most certainly, most absolutely prefer muscle on the average, but it comes down to how you carry it. For example, in the Rock Hard DVD, Gunter looked like a model despite his weight which was no doubt in excess of 260 pounds. I cannot see a woman saying he is too big at that weight because he carries his muscle well and his personality reflects in his physical mannerisms too - his smile and the way he walks and talks for example. He has since used too much GH which has made his face grow, but he still looks very good despite being as huge as he is. Contrast that with Branch Warren who has way too much muscle for his frame, is short, bald, etc, and I highly doubt there would be a lot of women attracted to his look. I know that's rude to say, but it is nevertheless true. Like I said, it comes down to face and how you carry the muscularity you have.
The guy in the pictures below was the biggest guy at my high school at 5'10 and 165...and to this day he is still 5'10 and 165. More muscle would not help him to get more girls, and I highly doubt Gunter would get more than him or vice versa:
