You’re 19 and you started 3yrs ago at 16? Other than some basic research there isn’t much you can do prior to 18 or 21. Unless you mean playing in online groups or acting out porn with people of your same age. Dungeons, clubs and bdsm groups are all atleast 18yrs and up most are 21 and up. So the odds of you having experience with someone who was 18+ and in the community is slim to none. no one would risk that with a minor back at that time even with age of consent laws. Some of your other posts here really shows your inexperience and now it all makes sense about the one I read yesterday.
That being said. The bdsm kink community is very open to people who own that newness and lack of Exp and reach out for help and guidance. So you will probably find much better results being honest here with what you know and don’t. A new sub with a new Dom can be a dangerous combo for both parties.
