I've been wondering why I like images of outdoor nudity (or semi-nudity) and images where one person is clothed and the other naked (doesn't matter which genders), and I've finally decided I find it just feels liberating. This is not just a fantasy, it is something that I enjoy actually doing too. It isn't exhibitionism (it isn't something that I want to do in a public setting), but being able to shed one's clothes in a safe environment with someone you love, either indoors our out, and have that be appreciated and accepted, is simply wonderful.
