Is it normal to jerk off in public?

Every time I go to school, I get uncontrollable urges to pull out my penis and stroke it like a mad man.

I do it at the back of the classroom, in the cafeteria, on the bus, in the janitor's storage room, and in the guy's locker room. In fact, I'll jerk off anywhere that seems exciting to me. The thrill of getting caught is such a turn on to me.

I'm now a college student and I've been doing the same thing just like I did in highschool. Except, I'm doing it in even more riskier places such as the library, underneath the staircase, and worse of all the "praying room" at my college where religious students go and pray.

I know that sounds fucked up, but I always get good orgasms from jerking off in the "praying room" at my college.
