I never had sex education classes as such. But in my last year of high school, when I was 17, a woman came to give us a talk about sex education. I didn't know it at the time, but I later found out that the school had organized this talk because a girl in another group in my year had become pregnant. The talk was equally uncomfortable, unpleasant, and revealing. The most uncomfortable and revealing part was at the beginning, because the woman asked us a series of personal questions that we had to answer, fortunately anonymously. After asking us the question, we had to write the answer on a piece of paper and put it in a cardboard box. On each piece of paper, in addition to the answer, we had to indicate whether we were a boy or a girl. The questions were along the lines of: Do you masturbate? Have you ever watched porn? Have you ever had sex? The last two questions were very revealing and shocking to me, because after counting the yeses and nos, I think it turned out that about two-thirds of the students had had sex at least once. I, of course, was a virgin. I don't know if even more shocking was the result of the question about porn, because of all the boys in the class, only one had never seen porn. That is, me. Almost all the girls had never seen porn, but of all the boys, the only one who had never seen porn was me. I am 51 years old, which means that when I was 17, it wasn't as easy to watch porn as it is now, thanks to the internet. Back then, to watch a porn movie, you had to buy it at a sex shop, rent it from a video store, or get someone to pass you the VHS tape. The most unpleasant part of the talk was at the end, when she talked to us about teenage pregnancy and, above all, sexually transmitted diseases. Here we saw lots of penises and vaginas with all kinds of diseases. It was really disgusting. Then the woman talked to us about the need to use condoms and showed us how to put them on. Unlike what I've read in other posts, the woman didn't use a fake penis, but instead took the condom with one hand and put it on the index and middle fingers of her other hand. At the end of the talk, the woman gave each student a condom. After the issue of sexual relations and pornography, the third revelation, and the most shocking and unpleasant of all, was when, at night, in my bed, I had the idea of putting on the condom to masturbate, because at that moment I realized that the condom did not fit me. I was perfectly aware that I had a small penis, but until then, the only thing that worried me was the length. From then on, I added the thickness of my penis to my list of concerns.
