Do you not think that LGBT inclusive RSE should include details of how a lot of gay and bisexual men have sex? Should kids only be taught the mechanics of straight kids?
When I was at school I knew that gay men had anal sex, I also knew that some heterosexual adults had anal sex. In addition I was also taught about the importance of wearing a condom during anal sex because of the higher risk of tissue tearing.
Somehow I was able to gain this knowledge without having anal sex totally normalised as something that everyone does, and constant 'education' about anal, fisting, 'docking' (or whatever it is called) etc.
Also, it's strange isn't it how 'LGBT inclusive sex' basically means male gay sex, or even male heterosexual sex? Lots of focus on which holes you can stick dicks or fists into, not much focus on how two girls, sorry two people without a prostate can find pleasure with each other.
