When I was 14 at school and I saw 2 guys kissing it was like, "Ewww, gay!" (but of course women doing it was sexy) But that's because my school back when I was a kid was a very homophobic environment. I un-learned my prejudices pretty quickly outside of school. It's not guys kissing, or girls kissing. It's people kissing. And these days whoever's doing it barely registers.
