Actually, it would have nothing to do with that guy being homosexual so much as it would have to do with him being an egotistical idiot.
I'm not so sure it's "NOTHING" to do... maybe little to do...
I mean.. we could easily imagine the situation where a male would be perving on a female by asking about her perfume..
If it happens for Male x female... what stops it from happening in male x male, female x male, female x female
So we established that It could happen.. for all permutations of gender..
Now.. we have to establish likelihood...
male x female perving, most likely...
male x male perving, second most likely
female x male perving, 3rd
female x female perving, 4th
