Oh yeah forgot about Otters and the other subcultures?...
I think amateurs refer to sexual acts without prior experience? idk
Yeah, the subcultures are just... Urgh... SO many terms. ._. I mean, Wolf, Bear, Cub, Twink, Otter, Bull, there's so god damn many. It's honestly confusing at times. All I can say is never deal with people or porn using the term "pozzer" or "pozzing". It's a very disgusting fetish about spreading sexual diseases, HIV and AIDS too, and a very hard lesson to anyone who doesn't use protection.
And Amateurs is kinda a trick question cos it means people with little to no experience, but also just refers to people making porn who aren't actual pornstars. Sex tapes and stuff.
If I feel like I'm lecturing, sorry, I have a habit of excessively explaining anything I know. ^^"
