I don't know how to answer this question really. I have been in certain business and social situations and have been hit on by woman; so I suppose when I am dressed more formal and acting like a grown up I might appear differently ... I was shopping with some friends once and the sales person said to me... "Ohhhhhhhhh so you are the friend that know how to accessorize!" I think we can give different impressions in different types of situations.
I don't think I've ever been perceived as straight while I was cruising in a gay bar. A few ladies at a fancy party in Palm Beach made no secret that they would like to get to know me better (I don't know if it was the testosterone pheromones I was exuding or the fact that I was wearing a Rolex.)
This might be better answered by the few LPSG members who have met me in person.
