Why always gay?!?

I'm not gay and I'm still watching these images...

Maybe sounds weird, I know, but the reason of why I'm watching these images is, that I like cute things like my little pony ponys, lions, foxes... and I also like great artwork like this picture.

AND when I see cute things doing loves highest state I really get lots of pleasure.

But I still don't understand why there are so much gay pictures.

I hope that people do more heterosexual pictures.

Thank you.
