Also speaking as a woman, at least in this instance, I don't find women's bits interesting, however I can look at a woman either clothed or unclothed and think that she is attractive. Not in a sexual sense but because she has a nice body, is wearing clothes that suit her the list goes on.
I can look at men in much the same way although your men's parts can be a tad distracting. When the first blokey mag for women was published I was about 16 my aunt purchased a copy and the centrefold was a very attractive fit young man on a windsurfing board, all well and good but his willy was just sort of flapping about, sexual appeal for me would have been same young man same pose but wearing shorts or summat.
Will try and find some pics later.

Stunning in IMHO. Her nude pics are great. Would I have wanted to fiddle with her wummans bits? No. Am I turned on? No. Do I have the urge to stare at her wummans bits? No. Do I think she is stunningly attractive? Yes.
