I learned a lot about the human reproductive system in both male and females while I lived in Maryland. I moved to Texas and I learned that women are sinners and so they suffer every month and men have OP rib bones.

Not embarrassing, just disappointing.

Precum contains next to no sperm, so it's really unlikely to get pregnant from it. Apparently Sex ED universally exaggerates that chance so that people don't get the dumb idea to rely on pulling out.

I mean it's probably the right way to teach it that way, but you know, if someone theoretically had a bit of an impregnation kink, it sure would make them sad :(

I learned way too late about the fertility cycle of my female reproductive organs. What, I can feel my cervix, if I just reach into my vagina deep enough?! And oh, so during my fertile days, my vulva will get slippery, my cervix is soft like my earlobe, and my cervical mucus becomes stretchy like egg white?! Also, my body temperature rises?! And on the not-so-fertile days, my cervix is closed, feels harder (like the tip of my nose), and none or less mucus. That's wild, so much to learn about a body that I thought I knew!

(You can use these observations to contracept or to become pregnant, but if you do, please inform yourself about Natural Family Planning (NFP) or the sympto-thermal method. It takes a routine and some experience for it to be reliable, but once you get the hang of it, it is awesome!)

Not my info but this year a classmate confided in me the following:

"it took an embarrassingly long time to realize that men have multiple holes on their penis".

I thought she was joking but she was dead serious, (she was from a very conservative family to put it mildly and had been withheld from sex-ed their entire life). For some reason they insisted arguing about it with me and the other guy present.

I was 22 and she was 21.

Didn't realize that being ace was a thing, people keep assuring me that sexual attraction "naturally" happened

Not sex related, but I learned it in sex ed. Most males do not have a big depression in their chest. Turns out that the males in my family happened to have a condition known as Pectus Excavatum.

idk if 'embarassingly' late, but, I assumed that doggy style was always anal, and vaginal sex was missionary for a while lol.

I had a friend once who thought that doubling up on a condom meant double protection. That's a huge no no.

I think we had the basics covered early. Too early maybe. I remember holding a presentation in grade school about AIDS, but that was half made by my grandma and I barely understood what I was reading from my papers.

I thought chocolatemilk came from brown cows 😭
