Masturbation

[Rowan]

Nothing wrong with waxing the dolphin.

Its even normal to do it when you're in a relationship.
Never been caught, although i've been close to being caught.

Stealth penis.

[Xanatos]

Of course, whenever I'm in a mood for it. It's something I have to do right before I'm about to study as it helps me relieve tension =D I have a lot privacy during the day, it's nearly impossible to be caught, though there were few sticky situations I got out more by luck than anything else.
