My wife has nude photos of me on her phone (including closeups of my package) and she's told me that she has shared some of them with various girlfriends. She tells me that they are all appreciative.
The women who have seen them don't know that I know, so they're not at all shy around me. It's fun knowing that they know what I'm packing and I notice the glances they make at my crotch whenever we get together!
