Well I will say something here, and I don't care if it is just another reinforcment of double standards.
Men generally don't like looking at pictures of men. I am more likely to have pictures of my girl posted than myself.
Also, if I saw a bunch of pictures of a guy in his profile and or album (showing off his body etc), I might be so inclined to think he is one self centered sob at first glance.
Conversely if he has no pictures I would tend to think he eaither isn't on the market for a sub, is hideing a beer gut or worse, is just plain lazy, or not serious about finding a potential mate and just here for the cyber sex.
Though in all honesty, if I was on the market and trying to attract a girl, I would post some pictures. Not because it's "fair" or anything; but, mainly because it is some topping for the cake.
Look at nature, it is allmost allways the male of the species that does all the showing off to attract a mate, even amongst us primates.
