Straight guy here. Years ago I went through a phase in which I enjoyed putting things in my ass. I started with small butt plugs and worked my way up to medium sized butt plugs. Recently as a spur of the moment thing I decided to get a new medium sized butt plug and some water based anal lube. I know I should’ve started small but I guess I was overconfident and thought I could use a medium sized one since I used to be able to. I lubed up and tried to get it in a few times. It kinda hurt and felt tight so I switched to fingers. I got one finger in, then two. I was sort of fingering myself and rubbing different spots including my prostate. All of a sudden I felt an uncomfortable feeling like I had irritated something. I stopped what I was doing completely. This morning it felt slightly painful when I pooped, and then throughout the day I can kind of feel a mild dull pain/discomfort. I’m kind of paranoid about hurting my ass because a close friend of mine has dealt with anal fissures and it sounds horrible. I really never want to have any kind of issue like that. So I’m kind of upset and wondering if I’ve caused any permanent damage? Or will it heal completely soon and go back to normal?
