I got the same with some straight girls and just answer with " don't worry, you're not my type anyway " and leave them feeling like you called them a terrible name
But isn't it more selfish to demand other people to go against their nature just because you don't like it?
They're not hurting anyone, why do you care?
Guest, even though it's only 4%, it's better to allow us to like whoever we like because then we can live happy lives and not have to hide from society. If I was forced to marry a girl, I would seriously be depressed, probably to an extreme point. And homosexuality isn't trending, it just feels more common because more people are coming out and are happy liking who they like
