Well, all pussies are NOT created equal. If you think you have a pretty pussy, then you should show it. Some guys may say they like them all, but I sure as hell disagree. I appreciate a really attractive pussy like a work of art. If you truly have a pretty pussy, it can only help you to show it off.
When I look at an ad, I look for face, then ass, then boobs, then the Y.
While I may see a provider without any of the aforementioned pics, it's not very likely, and would only be on the recommendation of someone I trust.
I am very superficial. I like beautiful women and beautiful pussies on women. A good face shot or Y shot gets me every time.
Just my .02
