My mum at least asked ‘do you learn about this stuff in school?’, to which i awkwardly said yeah. We did get some pretty good classes on bodies, the biology of reproduction, and contraception. I even remember having a test on contraceptives in biology class.
Unfortunately, it was very cis-het only. I had to figure out by myself that I should be using protection during sex even if both participants had a vulva.
As for drugs, it never occurred to my mum that anything other than alcohol and nicotine could be relevant to us. She did well on keeping me from smoking just by telling me about her experience as a smoker and how hard it was to quit. I kept my drinking and weed smoking from her pretty well because even a mention would make her angry. To be fair, as an adult I understand she had some trauma from her mum being an alcoholic.
