It's the only way I can get off.
Is there a reason for that?
Yes. I need to feel that everyone's eyes are on me when I have sex.
Some people have unusual fetishes. That's not wrong in itself.
Fuck you. What is wrong with my fetish?
There's nothing wrong with it, necessarily, because everyone has different preferences. As long as you participate with other people who are consenting then you're perfectly fine.
