Signs my parents might know I'm gay?

I'm 19, Have a lot of insecurity at the moment, very worried my parents might know I'm gay. Don't really feel great about it. I'm really not sure if I want to know if I'm gay or not but still. I have some examples, maybe someone could help?prosI've always been really REALLY straight acting, I'm not very effeminate, I think I was pretty mature for the most part growing up. Never really got into trouble, ever, especially considering my mom knew some teen who assaulted his girlfriend and went to prison. I've been seen with girls flirting with me which my mom saw. (although unfortunately I never really showed any interest in the girls when my mom asked about them, but i doubt thats anything) Usually pretty responsible too, so maybe they think I'm just too busy for girls? Frequently clean up their house for them.consI'm tall, but also very slim, had longer hair for a while. Never dated any girls through high school. I've shaved my legs occasionally where I think they noticed, i don't participate in sports but i have bragged how fit I am, and I always have shaved my forearms, which my dad made a comment about..I've also mistakenly left some gay stuff open on my browser while showing her some emails occasionally, although at most it was just a thread kind obscured in another window, and a hidden window that was shown when I right clicked chrome really quick.My mom has also been facetious lately, maybe. She was talking to my aunt the other day and basically told her something like "I don't think (me) cares if girls come" Don't know the full extent of the conversation, but yeah.She also said something strange essentially implying that I'd never get married or have kids, then paused for a bit, kinda took it back?I don't really know. They're very puzzling sometimes.What do you think? Do you think they know?
