For a while I was really debating this, not knowing what to do.
My mom, in an act of kindness, fixed it all in one swoop for me. She said that her boyfriend (cismale) always sits. He said it's more comfortable to him, and easier. Now I have no qualms about sitting down. I'm still mastering my STP, so I think there will be days I'll sit, and days I stand. Either way, I rarely use the facilities in public (10 hour days at my work ain't got nothin' on me!), because I have a shy bladder anyway, but when I do, I sit. No one has said a word.
