I honestly don't care if someone is gay or straight.
However I still don't enjoy seeing men groping each other in public, it's gross.

I think that's normal. Gay people have grown up around heterosexual couples for the most part, so they're used to seeing a male and a female kiss. However, you and I aren't used to seeing a homosexual couple kiss, which is why it'd be considered "gross." I don't think we should forbid them from expressing affection in public, but uhh... I don't really want to see it either.
