I never really thought about this... but lately people are calling me "little" and "short" more frequently. I never receive little until now, and then a guy came up to me and said, "I would expect you to be bigger" because of my reputation of working out. On the other hand, my friends sometimes tell me I am good looking, and I know I am attractive and get female attention even. It's annoying when people are constantly touching me as well (to adjust something they think needs to be fix), but I don't get angry about it. Or patting me on the shoulder. And then someone had to say "come hither" to me and another short guy.
And it doesn't matter if the guy is younger than me, but if he's a noticeable bigger than me then he tells me what to do. That's annoying.
It's okay, but I don't think average guys get treated like this, at least I don't treat guys like this. And then, when someone finds out how good my fitness level is, they act shock, like it's not possible. It's base on how my body looks.
I am 5'6, nearly 5'7, and look about 20. But also the weight on my body has adjusted to become more muscular and less fat, so I look thinner but weigh the same.
