I don't think I'll ever get dom/sub or sadism-- I get them on a psychological level, I can see how someone could possibly enjoy them, I can see how pain and other sensations can go with pleasure, I like bondage in and of itself, but I don't see the appeal in dom/sub or sadism or real masochism and I don't see how they could feel right or natural to someone that's not messed up in the head or someone that hasn't tried and gotten bored with everything else. Also feet... I keep seeing people say they're naturally linked to that whole setup and a bunch of ancient and modern cultures consider them linked and even important to those feelings and tendencies, and I know there are often accepted standards that can be used to judge them as attractive or not, but I just don't see it, to me they're just feet. Other than those I can either see the appeal or see how someone could just grow to like all the other ones I can think of.
