trial and error mostly but there’s been help with standard movies that mocked the troubles of puberty, standard sex ed books and me, the nerd, who at 14 picked up at the library an old copy of:
Alfred Kinsey’s Sexual Behavior in the Human Male
because i wasn’t satisfied with “sometimes stuff makes u feel good just be careful lol” and i wanted to know about the RANGE of behavior to see where I fit in. (I’d also read Guinness Book of World records which used to be a thick book of stats and facts – I was a fact junkie, not that I could remember any of it).
So Kinsey didn’t teach me but Kinsey taught me about male behavior as it was statistically discovered through the 1920s and 1930s and written up in a large controversial tome full of statistics and odd little stories from across the USA published in 1948 and was still at my public library when I was young in the mid 1980s
