this brought back a really similar memory of mine i'd totally forgotten about.
on some random vacation with the extended family, we were all sitting down to dinner and, being a fidgety tween, I ended up sitting with my legs folded under me - mostly because that's the position I was in when a box of hush puppies came within arm's reach and that was all I cared about after that point. my dad noticed, got extremely alarmed, and told me not to sit like that - when i asked why, he got uncharacteristically evasive and said something like "it's girly, people will think you're, you know, [some euphemism for gay i don't totally remember]". there was a pretty awkward silence, i became aware everyone was looking at me, and a few uncomfortable seconds later the conversation moved on to something else. it's dawning on me that that was the first time:
now as it turns out, i'm lucky enough to have pretty great parents that were barely phased when i came out to them 5 years later, and have been entirely supportive of, if slightly awkward about, my sexuality ever since - which is what makes that memory so weird to me. granted, it was 5 years earlier, public attitudes just had a ways to go still, but my parents had been good friends with a lesbian couple since before i was born. i later learned my dad had written pretty extensively for a gay magazine when he was low on cash in his 20s. this wasn't a new world to him or my mom.
he was a less-great person back then, though, and had some anger issues which sort of messed me up a little as a kid (he got better). i dunno. i think i'm just going to be content with my parents and the people they are in 2017. do any other gay guys have stories like this? maybe it's something everyone's dad does at some point. (although /u/LilymonX, i don't mean to suggest for a second that the way your dad treated you wasn't 100% abuse and just plain old dishonest and shitty; screw him. hope you're doing better these days.)
also: i'm masculine-ish, and i do the crossed-legs thing all the time. for me, it's the first move in the incredibly awkward social dance of "this guy in a professional setting is hot and possibly gay, how do i confirm he is gay and then also let him know i'm gay without directly asking or saying either of those things".
