Why would I want to purposeful tease someone staring at me knowing that even if his staring meant he was sexually interested in me, I really didn't want to do anything with him? Why give him the mistaken impression I was either gay or leaned that way and interested in him, when I was instead just using the attention for my own ego? Sounds kind of like a dick move to me.
Some guys don't like it or even get upset when certain women do this to men and go out of their way for attention and string them along, even though they have no actual interest in that man. So how is this any different?
How to you also judge the guy is staring for sexually reasons? People glance or stare at each other for several reasons and for guys, a lot of it has to do with dominance or it can be seen as a challenge. How might someone (an actual straight guy and not a "straight" guy) respond if they were looking at you for a non-sexually reason and you started throwing up signs you might be interested in them? Some might not respond very well.
So, no, I would not do this to other guys and I don't like them staring at me, particularly when I cannot be sure of their intentions.
