TNJ, I'm going to play devil's advocate here.
Think of the view we get, especially in doggy, if we turn. We see our partner upright, in a primal state (especially when they start to lose their mind, pre orgasm) and we can see their appreciation of us.
Pretty cool.
For my partner's part, they get the rosebud and a birthmark, and jiggling. And in my case, lots of hair tangling everywhere. #kneelengthhairproblems.
Oh don't get me wrong... I love the way he looks when he's fucking me. It's hot as Fuck. When I'm laying flat on my back,or when I'm bent over and look back at him just, Hitting that shit.. oh yeah. His broad shoulders, the look on his face as he's focusing on that view I'm talkin' 'bout... it's all very appealing as well.
However, I have to say, I like the rosebud. Butthole is sexy as hell to me. One of the best pics in my gallery IMO is the one he took of his dick just about to go into my fine-booty-hole. It's quite attractive to me. Jiggling is also sexy as hell to me. I also find scars/birthmarks to be a turn on. And hair? Hair is also sexy as all hell... especially long hair that shows all the evidence of a good round of hot, sweaty sex.
I do get your point... but I still stand firm, I wanna see it All.
