At the rate this is going the next thing will be teaching kids about is double/triple penetration of the vagina and/or anus with a dick in your mouth and that it can be totally safe and okay if you use plenty of lube. Eiffel tower anyone? Surely they need to know about that too? 🤮
You know what may deter many kids from committing most sex acts before they're ready (beyond kissing and before penetrative sex acts)?
Give them access starting at say 11 - 13yrs old to nursing manuals about STIs paired with education - that should stop many of them in their tracks.
Approach it from a medical perspective from the arena of bodily harm and long-term consequences using correct terms (vulva: labia minora/majora, vagina, cervix, uterus, fallopian tubes, follicles, ova - you get the picture) and following up with descriptions for each of those words if necessary for understanding based on age and terms they use to tie into their current conceptualization. Core lessons: reproductive organs, their function, what bodies they belong to (female or male), potential for pregnancy, and potential for bodily harm from pregnancy or sex acts.
I was lucky enough to have a female RN as a parent - who took the time to draw diagrams and explain male and female reproductive organs and associated gametes as well as the potential for pregnancy and physical harm as a result of penetrative sex. She then followed up with handing me her purple nursing textbook on STIs that was about 1,500 pages long with full color photos of affected genitals/mouths/anuses, and descriptions of the STIs shown. I still reference that book to this day. Core lessons: STIs can destroy your genitals/anus/mouth/throat as well as your immune system and can kill you or leave you mentally and/or physically incompetent forever.
We also discussed consent and the need to not only say no but to kick, bite, scream, scratch, punch, whatever to get away if the "no" is ignored. We discussed the importance of: mutual pleasure in sex acts and communication for the safety and enjoyment of parties involved. Core lessons: always exert and enforce boundaries, importance of acknowledging feelings of discomfort and denying suppression thereof, using force to escape if your instincts scream danger.
Yes I was lucky in that respect and I realize most children may not have access to a parent/guardian that competent in relation to Sex Ed. Because we had those conversations I did not fear asking her questions I asked her about every bizarre thing I heard about and she did her best to answer through the same lens described above.
That is the standpoint that Sex Ed should be taken from IMO not the site's dumbing-down and normalization of fetishistic and paraphilic behaviors.
Coming at it from that perspective opens the doors for questions as well as educates.
