Visible moistness / excitement

We all know how revealing, even embarrassing, it can be for a male to be sexually aroused; I had my own uneasy times at the swimming pool as a teen with a hard-on. I wonder if something similar can happen to females - getting excited to the point that vaginal moisture or other sign of arousal (nipples?) gets visible. Or at least if, even if it's not visible, the woman feels her own lubrication and gets embarrassed from that.

(I'd like answers from women about their experience. If men want to tell what happened to their female friend etc. go ahead but please don't make this a conversation of males saying what they would like to happen to women!)
