“Definitely thought blowjob was literal, like she blows into it like a kazoo. Was racked with guilt about masturbation and wet dreams because of all the babies. I had a friend who thought the same about peeing. Also, sex freaked me out because I thought she had like a tube or something in her vagina that was supposed to go in my penis hole.” –dh9690

“When I started masturbating, I thought if I kept doing it, my testicles would shrink to nothing. I thought women just got pregnant at a certain age. Whenever I pictured two people having sex, I imagined the guy doing “the worm” on top of a women.” –GageTorrance

“I thought sperm were the size of tadpoles. I thought they shot out and filled up the condom like a water balloon and you would be able to see and hear them slithering and wriggling around. Needless to say I was scared of sexual maturity for a while.”- FractiousBetaMale

“I heard about sheepskin or lambskin condoms when I was a kid and for some reason imagined a guy wrapping one of my rabbit pelts around his dick and trying to get that into a woman. Never occurred to me they’d just use the skin and not the whole hide.” –BobaFettuccine

“I thought any TV show I saw that wasn’t a cartoon(or at least the majority of them) were entirely sex related movies or shows. Because any time I would ask my parents to watch them, they would say I wouldn’t understand. And they also said that whenever I asked about sex-related things, so I grouped it all together that anything that my parents told me I’d “understand when I’m older” was entirely about sex.” –Cr1msonFoxx

“When I was 14 I thought anal sex was when a guy just f-cked your buttcrack like literally just sliding his dick between the cheeks without ever entering any hole and I was so confused.” –cartoonsandscience
