I'm dealing with that issue too, there are some thoughts that make me believe that I'm gay even when I dont like the idea, I'm not interesting in that, I'm bad at sports too, I dont feel confortable with perv. talk and so on...
I'm a Mechanical engineer so I spend many hours with guys at the plant and sometimes I feel weird and different too when they speak, but there is sometime that works for me... I say to myself that maybe there are moments when I dont know who I am but I do know who I want to be, that everything is gonna be ok and I just have to know how to work for it..
So try to stay quiet, look for therapy to face those feelings, calm the anxiety and like other survivor told me in this forum... go one step at a time... best wishes.
PD: I'm not an english speaker
