Not just same sex, but interracial relationships, girlfriends and boyfriends, and ex-lovers reacquainting. Keep in mind that we're not joking. We really think that there is a lot of sexual inhibition and people feel embarrassed by such things. Let's get out of the Ice Age. People, we should be making out more often and more publicly.
How many times have you wanted to kiss someone in public, but didn't want to hear, "Get a room," or, "They're really going to town on one another." There's no need for this. Romance is a wonderful thing, and love and lust are pretty interesting to get an eyeful of.
Imagine you're walking with someone you really like. Maybe they're waiting to kiss you and you can't stand it anymore. Say there's an opportunity in public that has to be bypassed. No longer!
Way back, a long time ago, someone got the notion that kissing should be a private thing. Don't misunderstand, we think it should be, but why not make it a public thing, too? It just opens the options dramatically. We don't know how this will affect holding hands, which we are big advocates of, but the effects should be limited. This will make people more comfortable with kissing if they aren't already. And if you're bad at it, just watch others and take notes. Notice: hands on waist, hands around neck. Don't act like a snake, and hands on the face can add to really powerful moments.
