Does This Guy Fancy Me (Gay)?

I am 24 and this guy at work, he is really nice to me, he is similar age, he is a bit feminine, his voice is slightly femme and he wears tight black jeans and a really tight black t-shirt, he gets me a coffee when I didn't ask, he talks to me, now most people talk to me but I usually have to make the effort, however he talks to me without me having to talk first.

I have slept with men before in fact I have only ever slept with men, so I can tell if a guy is attractive and I think he is gorgeous, in bed the other night I had a fantasy about him

could he fancy me? could he be gay?
