He already saw you once.
Yet suddenly every hotel-room change, gym locker and swimming trip has a little extra audience energy.
Novelty makes people look twice
Unusual bodies get attention. If what he saw conflicted with his assumptions about what other men look like, curiosity may persist.
Male comparison can also be sticky. Once another guy becomes a reference point, the brain wants more information: soft versus hard, actual size versus first impression, how different am I?
That does not automatically mean attraction
Straight men can compare men. Curious men can also be attracted. Both statements are true, which is why the behavior does not give you a clean orientation test.
The useful distinction is permission
If you are changing normally and he happens to glance, that is one thing. If he begins manufacturing situations, pulling at clothing, asking for pictures or refusing to stop after you say it is weird, the issue is not curiosity anymore.
Being interested in seeing something does not create a right to see it.
Use the smallest boundary that works
“You got your look already, professor.”
“Quit trying to see me naked. It’s getting weird.”
The bottom line
You do not have to figure out why he wants another look before deciding whether he gets one.

The calculator can tell you where an adult measurement falls in clinician-measured data. It cannot determine masculinity, friendship, sexuality, confidence, or what somebody else is thinking when they look at you.
