Let's put that to the test - has anyone here on AB ever in their entire lives ever ever ever seen a straight couple being asked to leave a pub, club or bar for snogging?
Yes, when I was 17 and it was me! :o(
I actually think I was being stupid and under the influence of too many vodkas. And yes I did drink when I was underage, most of us did back then in the 60's!!
Since'growing up', I hate to see people snogging in public, but don't find it offensive in any way. Just very attention seeking.
