I do get what you mean, there is a resturaunt next door to my Apt building and gay couples go there often. I just sit to where I don't see the rubing and touching and interaction, I'd rather be covered in spiders.
Now I'm not rude I don't leave or say something but I don't have a facination with seeing any of that. Same goes for hetero's I don't need to see people all over each other at the grociery store or the mall.
I get wiered out more by lesbians than I do men. Either way I just figure I don't need to be there. I just chalk it up to thats what they do.
