Autism =//= childish, especially as they grow up into adulthood. I mean yes, they do have child-like traits, and seek comfort within nostalgic objects and memories, BUT this doesn’t mean autistic peeps do not have sexual tendencies; they have can be as heterosexual, bisexual, gay, asexual, etc as any other human being.
For Tim’s situation, for those who don’t know, he’s demisexual; a person is not sexually attracted to anyone unless there’s a strong emotional foundation. Ever since Rich and Tim started dating at the beginning of sophomore, of course he wants to ask questions in order to make Timmy feel comfortable.
Tim certainly doesn’t mind any further intimacy and I think Richie’s…Richard doesn’t seem to mind either-
