I was 12 and had this friend for a year who suffered from Autism and I believe Tourette's too. Now I never thought he was gay, he never showed any signs until this one day we were in his room and he insisted that I held his thing because it's "something" friends do. I had to argue with him for 10 minutes about how inappropriate it was and it took him a while to figure out I wasn't gonna do it no matter how pushy he was. After that day I told him over the phone I wouldn't see him again.
So fast forward to 10 years later and with this experience of almost giving in, I just want to from now on be able to know if someone is homosexual so that I can know who to stay away from in case of someone inconsiderate who wants to engage in some inappropriate activity with someone who is straight.
What's really scary is that for an entire year of having him as a close friend I never saw any gayness in him, he seemed like guy who liked masculine stuff he wasn't girly in the slightest. He was definitely strange, he had learning difficulties and had constant ticks and harsh ones too. He would even talk about his interest in girls, lie about having a girlfriend with big boobs. He seemed quite heterosexual to me, and then the last day of seeing him and he insists of me touching his d because apparently it was a thing friends just do.
