I think geography may play a part in this. In some places man on man (hetero / gay) is just not welcomed. I live in California, my B/F and I hug and touch each other in public. I have also hugged and kissed male friends goodby after lunch in public. Maybe it's because I don't care what others think. WOuld I do this if I was visiting Saudi Arabia? I don't know. We have a house in the thousand Islands in Ontario Canada, and at times we get THE LOOK from people who see us and know were a gay couple. I think it's based on geography.
