Okay, just to illustrate something...
Back when I was working at Walmart, and still in denial about being trans, I actually forced myself to do EVERYTHING sitting for an entire month straight because my dysphoric brain felt like it.
Nobody cared. Nobody said a word to me. And for God's sake, I was wearing pink panties, which very well might have been visible around my ankles if anyone cared to look. Nobody did. Not so much as a word about either thing, even though it was in the store's very-public bathrooms.
If anyone in a men's restroom sees you sitting, they just automatically assume that you're taking a crap and leave you alone. That's it. They won't even think twice. They won't look, they won't think, they'll just migate to their own stall and pretend that you don't exist. That is how little guys care about their other gendermates' bathroom habits.
(Side note: honestly, if you ask me, anyone who refuses to pee while sitting down, even when they're doing #2 anyway, has some serious insecurity problems. The first time I heard that there really were some guys who did this, I was like "OMG, are you guys stupid? Wow...")
