It's funny what we're attracted to. I like seeing stiff nipples on small, perky breasts, but it doesn't "do" anything for me, it's just attractive. Cameltoe on the other hand ... that makes me hard. I love seeing it. For neither of them are there judgements. I may judge you on OTHER aspects of your appearance and/or behaviour, but not on that.
One of my FWB always makes sure that something is noticeable. Nips, camel toe....whatever. She likes to watch men trying to watch her and we talk about it after. And yes, after a while, her nips get hard and she gets moist. Doing it for years now.
My ex wife has prominent outer labia. She enjoyed wearing biking shorts during and after biking because her obvious camel toe was on display. She found that by shaving bare, her camel toe gave a cleaner presentation. She also liked them on men because she could see everything they had, especially if they were well endowed. She said with both sexes wearing the shorts, there were no surprises when the clothes came off. With her, the clothes came off with all of the single guys in the club, and a few married ones as well. She jokingly referred to herself as the club bicycle: "Everybody gets to ride me." She is Jean in my Exhibitionist Women blog.
