Like lynn said, it is actually fairly common of a fetish to have. Everyone is different and enjoys different things. If YOU feel it's a problem then maybe you should look into potentially how this fetish came on. If you don't have a problem with it, then it's not a problem. And whether a partner chose to participate or not, sharing something like this can really show you how a person feels about you. It's no different than having to admit any other baggage or issues anyone else has. I'm sure some people would say some of the stuff I enjoy is weird (for instance there are over 20 boxes of bugs in my office lol) but who cares? I'm a weirdo and proud of it!
