I 21M, grew up with a religious strict background (been taught sex is only after marriage). but I'm really horny for someone who's a virgin, and I fantasies in having a threesome. But want to explore kinky stuff by myself because I get too shy to talk to girls. whenever I try to masturbate I can't cause I feel like the inner guilt is eating me alive. Any advice to satisfy my horniness and kinky stuff without getting caught
