I am male, 25 and in the closet.
There is a male co-worker at work that I know is gay (he hadnt told me and I hadnt told him). I started saying hello to him and asking him how he's get on with work related things.
Then he kept staring and glancing at me regularly - we just seemed to look at each at the same time. He also made a point of getting my attention a number of times.
But since I am in the closet and shy I got nervous with his intense eye contact and kept looking away. I even started avoiding him and he seemed to avoid me - but after all that I still maintained a good friendship and kept talking to him depsite not knowing him that well.
He has never asked me if I am gay - and the whole situation got me down so much I made a fool of myself one day and said,
"Can I talk to you sometime - I could do with some advice' he was so distant I just said ' it doesnt matter'
Now I never see him he just seems to avoid coming anywhere near me - the glances are still happening but not as often.
