Rick, my husband plays in the bathroom all the time and his performances aren't carnal either. He says there is a lot to be said for tile and there is limited likelihood of a bunch of wankers coming in to listen to him while he practices. He doesn't think your sick, you just have to remember not to drop your pants when you sit down to perform in public. For good or ill small cubicles in public washrooms have caused a lot of guitar players to convert to mandolin.
