I was on dating sites for years. I probably went out with at least 150-200 women. Many of their profiles would say things like "don't ask for nudes". What would they do during the first day or two of texting? Send nudes!
I don't delete anything so I have what was sent to me. My best friend also has copies of pics I've received. I also have pics of my ex-wife and some long term girlfriends. I find some women don't want their pictures taken because they worry about what will happen to them later. Others don't care.
