NC and was in two minds about posting but it is about someone's sexual orientation and since that's none of my business (apart from where it impacts on me, which will be my question) I don't want or need to discuss IRL. Will be brief as on tablet.
New colleague started 6 months ago. I work closely with him and we sit next to each other in a small space. After a couple of weeks and some things he said I assumed he was gay. Some of the factors include being late 40s, never married, lots of female friends that he meets for coffee and coddles and some personal preferences as well. I therefore hadn't been too worried about stuff like legs brushing, hands touching accidentally etc and as he is a very warm person, touches on the shoulder (which he initiated - I am very protective of my personal space I am always careful not to make someone else uncomfortable) and so on, whereas having seen a few mishaps in the office and people gossiping about others I am always very careful with most male colleagues in a way that i dont care with my female colleagues. And I know the ridiculousness of that, being bi myself, as anyone can be with anyone, but that is how things work in our office. Not without cause tbh as a significant minority are shagging each other right left and centre!
Over the past few months our boss has made a couple of cracks about me attracting older men like my colleague. I just shrugged it off as I wasn't about to gossip about someone's orientation.
I have spent the whole of today with colleague out of the office, the first time we have spent so much time together since I split up with my boyfriend a few months back. Two days ago he made a completely out of character 'joke' to our boss about straight top shelf magazines. it was so out of character (he's a gentle, feminist leftie) that neither of us knew what to say... it felt like he was trying to make a point but i wasnt sure what it was. He made several comments today about how attractive a number of women were, more comments about propositioning a previous female colleague and generally acted a bit boorish and completely out of character. By 3pm I had decided I'd definitely made the wrong assumption and felt like a bit of a tit but he tried to help me with my bag on the train home and our hands collided and he went bright red. I then endured 2 more hours of him telling me all these stories about how attractive various women were.
I'm very tired so not sure if I'm being an idiot. I think I need to observe the same bounds of propriety as I do with my other straight colleagues (there are some openly gay guys in the office and we are all more relaxed together as there's no hint that we could suddenly jump into the sack). But then I'm worried that I'm overthinking this. But then if he is straight I actually wouldn't be comfortable with the amount of casual touching and relaxing of personal space that we have. But if he isn't then I don't want to cause offense by suddenly being a bit more stand-offish.
I suspect am being an idiot but I'll post anyway and go with the majority.
