Drives me up the wall when it's the 'feeling uncomfortable about your body' one. For teens. Like bro, have you ever MET a teen? Just about everyone is uncomfortable with their body at that age because puberty does a number and a half on you! It's a sign of puberty, not of being trans.

The autism bit does not surprise me and def needs more looking into with the amount of autistic people that are trans. There's a link there but whether it's the autism itself or other factors would be interesting to find out. I suspect it's a bit of both. Like if you're putting things in boxes and something is outside of it and trans explains it? You probably need to talk with them and let them know men can like feminine activities without it making them not men. I do think that the 'acceptance' in the group is a factor too, especially when they likely have not found a lot before.
