In my experience on Grindr, guys are all over hung tops like flies on shit, regardless of anything else about them. Certainly I have to fend off a lot of guys who think that because I'm hung, I MUST be a top sex god (I'm vers, but I get tired of playing top all the time, ya know...)
As for your question: Faces are one of the keys to my sex drive, and a guy with the right kind of face can totally turn my crank, even if his body is not all that. That said, I'd be curious to see your face, because we are all our own worst critics, and beauty (or ugliness) is in the eye of the beholder. For years I thought I was homely (not ugly, just not particularly attractive), and now looking back on pictures of me from my 20s, I wonder how I could have been so blind to my own charms. I'm not my own type, but hell, yeah, I was good-looking. Most people under 40 in developed countries are - health care and the lack of childhood diseases and accidents have made for a population of largely beautiful people.
