The treatment sex ed as being risk assessment and harm reduction strategy is incomplete without some key points that also protect people having sex for recreational purposes specifically ones that LGBTQIA people tend to use as their primary forms of sexual engagement. Like if you don’t have a segment on anal sex with information about how it makes some STIs more transmissible, how anal sex with female partners is more likely to cause injury, and yes some basic pointers on techniques for making it safer for the people who rely on it as their primary form of being sexually intimate then you do leave people open to :
Higher physical risk of injury when experimenting with sex.
being potentially pressured into something with unique models and techniques needed for truly effective STI reduction.
people believing that it’s ultimately less of a big deal or life course altering because “you can’t get pregnant” so treating those behaviours as less risky
Removing or omitting sex ed that does not mention other risky forms of sexual intimacy other than heterosexual reproductive sex means you are creating blindspots of safety for everyone as many forms of sex like anal have become culturally prized even in heterosexual relationships. The prudish idea of “we can’t teach them techniques !” often stands of the way of fully comprehensive safety instruction leaving some demographics out in the cold as privileged people continue to treat those forms of sex as taboo and stigmatized.
