I am a gay guy & when walking around town I often eye up straight guys. I love checking out good looking guys on the train or passing me by on the street. It's especially good if they've got their trackies on, which show off the outline of their cocks. The question I have is, do straight guys realise that they are being eyed up, or do they always see another guy look at them as an aggressive thing? I'd like to know your thoughts.
