Same as a lot of people - it's just common sense. I don't want to see a gay couple absolutely going for it on the bus, in the same way that I don't want to see a straight couple going for it on the bus. On the bus everybody should just be sitting still and quiet! Couldn't give a hoot if they are gay or not, depends on the level of the 'kissing'. Just wait til you get home!
