So...
I've always been quiet and never had much sex. That has changed. I'm in the kind of phase that people look at me and say: "You were so nice! What went wrong!?" And now I'll have sex with men, women, ~~hookers~~ escorts, ~~removeds~~ not fully transitioned MtoF transsexuals, robots, I'll probably engage in BDSM, piss play, breath play, and other exotic activities. I won't engange in drugs/chemsex that's where I draw the line.
Thus, the advice I've always been given and followed looks a little inadequate. Somehow saying to just use condoms, pills and IUD looks like insufficient knowledge to the kind of behavior I'll engage in.
Therefore I need to up my game into sex ed and STIs knowledge and prevention. I've been looking inton PrEP, but I really need to read more about diseases and prevention to protect myself and be able to treat myself if I catch something.
Any suggestion of videos, books, and other learning resources that goes beyond the "just use a condom and have a single partner?"
This is wonderful and detailed advice but you can combine the circumcized and uncircumcised points. Studies on circumcision having any medical or protective benefit have been highly influenced by religious interests. The biggest ones by the Bill & Melinda Gates foundation in the 2000s look like pure philanthropy on the surface but people involved were calling for mass circumcision before they did the study. They draw a correlation with questionable methods that people who received free circumcisions in Africa had less cases of AIDS, which could be from any number of social or economic factors even if the data could be trusted. Medical organizations do not consider it to be a benefit.
