You know how most people are afraid of being "outed" by like walking in on them beating off to a clip, or having their YouTube suggestions bringing up videos or being called out on a party "Say friend, why do you keep tickling all the girls?!".
I'm afraid of being "outed" posting here. I'd whack my bag to Tickle Room videos in a crowded room before I ever admitted to posting on here. I don't understand why a forum full of (presumably) adults are so fucking strange but here we are.
I think a lot of it has to do with the freedom of anonymity, and the fact that a good portion of the "community" have never actually taken part in the act. That kind of resentment can come out in ugly ways.
