Yeah. It's less work, her tits are right in your face to suck if you like suckin tits, and you can play with her ass if you're an ass man, like me (LOL.) It can be better than doggy (LOL.)
I had one GF that liked to tie me spread-eagle to the bed, suck my cock hard, and ride me as hard as she could. Guaranteed mutual orgasms every time.
