Just learned that you can peel your foreskin???

I was just browsing the internet and found talk about proper sex, masturbation and sex ed. It had talk about if whaling was necessary and what to do if you hadn’t after puberty (I haven’t). It mentioned about peeling off your F-ing foreskin. I didn’t know what foreskin was. So I later tired it later in the bathroom and it turns out I have another D? Jokes aside what do I do with this information? Do you clean regularly? Should I get whaling later? I just have too much questions. (Im wondering if i should blame the lack of sex-ed I had or that im genuinely not interested in sex)
