When I was a kid, whenever a kissing scene came on in a movie or a show, even a comic, I would turn away until my parents told me "It's done", with weird looks at me afterwards. The scenes just made me feel super uncomfortable, and they still sort of do. It's the same thing with all those shirtless scenes that some movies would have.
Also, when people started to get crushes on each other and talk about that stuff, I just... didn't really fit. My friends would sometimes come up to me and say "isn't [insert stereotypical name here] hot???" or "i think i have a crush on [insert another stereotypical name here]." and I would sort of just go... "alright?" because i didn't know how to respond to that. I had never gotten a crush and I didn't know what it felt like, so I just went along with it thinking that "I'll feel attraction someday."
The only "love life" I have ever experienced to date was in elementary school, when my entire grade thought this one kid and I were together simply because we were both the shortest people in the grade level. The thought kind of just repulsed me entirely, to the point where I actively ignored the other kid who got unfortunately "shipped" with me. He was a cool kid, don't get me wrong, he was nice, and we got along well. We had a silent agreement that year and then on: Don't talk to each other, don't interact with each other unless necessary (school projects, plays, music class, etc). Thankfully, when the next year came around, everyone stopped. But that whole ordeal made me really realize that I didn't even like the notion of getting put into a possibly romantic relation with anyone else.
