I'm thinking I might fap at work behind the dumpsters.
Why do you want to masturbate at work?
I'm just attracted to the possibility of getting caught
You should not masturbate in public. Not only is it breaking a law, but you also risk losing your job. You should find an acceptable outlet for your sexual desires.
Should I masturbate to some old porn videos on my computer? Porn isn't doing it for me anymore, I feel like I've seen it all.
How do you handle your sexual desires is up to you, just make sure that you're doing it privately and not out in public. If your desire to masturbate in public persists, you should really speak to a mental health professional. I would hate for you to get caught and go to jail.
