Of course it would not turn you gay. Or would it?
Let me rephrase this for you.
In long term we, being social, unconsciously tend to become what people expect of us (becoming typically less malleable as we age) or feel tension otherwise. In an unrelated news, we seek approval of others. Those are sadly different things. If people see you (straight) as gay, and they disapprove of gay, you got a problem on your hands.
Maybe you see how that could introduce undercurrents that hamper your enjoyment at the bar.
