straight men like that 
Perhaps. My mom had a tight small ass. My dad was straight as an arrow and so was my stepfather. The both found her to be very attractive as did a lot of other supposedly straight men since she was always getting hit on at the beach when we were there. I think the whole Kim Kardasian inspired big butt thing is a phase that will pass. Trim athletic women will once again be the most sought after.
There was a time when the Barbie doll was the epitome of the fantasy woman all men lusted after. Vargas models didn't have over-sized shelf butts like people who are afflicted by the deformity know as steatopygia.
Steatopygia (/stiːˌætɵˈpɪdʒiə/;[1] from the Greek στέαρ stéar, "tallow" and πυγή pugḗ, "rump") is a high degree of fat accumulation in and around the buttocks. The deposit of fat is not confined to the gluteal regions, but extends to the outside and front of the thighs, forming a thick layer reaching sometimes to the knee. It often is accompanied by the formation known as elongated labia (labia minora that may extend as much as four inches beyond the outer reaches of the vulva).
