It's rare to see straight men, traveling around.

It's mostly because only gay men and women are desired by whoever they are trying to attract.

So it's only worth it for them to spend on styling, cloths, makeup, travel etc...

Travel doesn't produce ROI neither in terms of experience, nor in terms of attracting anyone so we see them traveling less.

This is one reason you'll rarely see straight men spending money on bullshit styling and travel. Why? Because it has no pay off, no reward = no incentive to continue the feedback loop, no reinforcement of the behavior.
