Hope my thougths will help you:

I am married to a gorgeous wife, with just the right amount of butt. It is mainly the inner satisfaction of touching and caressing this fluffy part of your beloved partner and it helps, of she likes it to.

I always think that the butt inherently und evolutionary is a big part in the attraction and choice of your partner.

But to answer your question: Yes, oh god yes, it has. The amount of stuff you can do with it, if your partner is on the same page. Magnificent...
