As a woman the pictures I consider sexy where the guy's ass is displayed..are the ones where guys wear sexy tight boxers and showing a bit of ass in a sideways angle..Where i can see his ass curve and how muscular he is..combined with a bit of view of the front..
Or guys wearing sexy jeans..showing that curve as well..
Those kind of pictures are sexy to me..
Pictures of just a naked ass being shown is boring to me..unless I see that naked ass..in that little more than sideways view ..
Pictures of a naked ass..bent over..or lying down showing a view of the asshole and balls..don't do anything for me either. To me they are more gay-erotic. They appeal more to my gay friends.. I have sat next to my friends often enough enjoying favorited pictures of guys we like from other sites to have a laugh often enough to see differences..
Does that make the men be less 'straight'.. well to ME..in my personal opinion ( which i'm allowed to have and share with anyone who reads it)..they aren't less straight but just more accepting of gay-eroticism.. But some here could also be less straight..
lets face it..who's 'displayed percentage' can you trust here
.
Men on here know that they are desired, admired, looked at by many men..so obviously you would like to cater to the variety of your audience as well..
But 'those positions' aren't done for my own personal enjoyment..that's all I can say..maybe it appeals to other women..don't know really.
