My workplace crush caught me mid change and I can’t stop thinking about it

So, I (29M) have a crush on a coworker (33M). He’s been my secret crush for a while, even though he’s straight and lives with his girlfriend. I’m a closeted, straight-passing gay man. We’re kinda friends and chat whenever we cross paths in the hallway. I rarely see him because working in a hotel means our shifts are pretty unpredictable.

I usually finish late around 11 PM, so the locker room is usually quiet when I’m changing to go home. One evening, I was getting changed and had just taken off my work pants. I only wear briefs (I hate boxers), and since I thought I was alone, I didn't think much of it. Even if I weren't alone, I don't usually mind being in my underwear since we're all men anyway. As long as there’s not that many people in the room.

Suddenly, he walked in. I could only see him through my peripheral vision, but I definitely didn't expect to see him that evening, it turns out he was scheduled for the overnight shift.

As he walked past, I could see him through my side-eye; he was looking at my legs and my butt the whole time. He literally stopped for a couple of seconds just to gaze down. I’m Asian and have very smooth legs, and since he's "straight as an arrow," I figured he just wasn't used to seeing that lol.

I’m not being delusional—I know it probably doesn't mean anything—but I just haven't been able to forget that interaction. Just needed to get that off my chest.
