So, I posted a few days ago about a situation I'm in, and got some negative responses, so I deleted it, but now I need further advice and hopefully, you guys will give me advice and not be cruel and nasty with your answers.

So, basically, my gayday is broken and i can't tell straight from bi or gay. I have a tendency to fall for the straight ones and i don't flirt because i dont know who I'm dealing with and don't want trouble. Anyway, there's a guy at my job who is married but has been giving me mixed signals and appears to be flirting with me. I've been with married men before (please don't judge me!) and except for ones I worked with, I didn't seek out the others. My big issue is that today, as I was walking past this guy at work, he said "damn, you're so sexy". I know I'm not, but I know some guys find me attractive. I honestly didn't hear him and asked him to repeat himself. He stuttered and replied that he was just talking to himself but loooked me right in the eyes and whispered the same thing again. ter he said it, we kinda just smiled at each other and went about work. I am NOT out at work, so no one knows I'm gay, but I'm just SOOOO confused. This isn't the first time he's said something similar. I can't tell if he's just fucking around and joking or if he's serious. He's kinda my type, but a little older than my type. What do I do?????
