I had some fantasies of wrestling, or rubbing on another guy when I was a teenager, but I never had any friends who were really "physical" enough to try it with. My cousin tried wrestling with me once (in a non-horny way), and I discovered that fantasies are very different than reality. I didn't like the feeling of being pinned down, so I told him to stop, and he complied. Thus ended my wrestling fantasies.
IDK, I'm not very "sporty" or physically active. Sorry if this isn't what anyone is looking for, but it's all I've got!
