Being HS messes with your mind
One of the oddest things about being HS is that you can't control who you have sexual thoughts about. You can either embrace it, and feel all the sexual thoughts, or suppress it and feel none. I find that while I have sexual thoughts about people I consider attractive, I find myself having sexual thoughts about people I am not attracted to at all, as well as people that I should NOT be attracted to. Some days I enjoy it, and some days I hate myself. People without our struggle will never understand how it feels.
Just putting this out here as a disclaimer: having sexual thoughts does not mean you are acting on them, just that they flood your brain and you have to find some way to deal with them. Being able to not act on them is the difference between HS and Sexual Addiction.
