Is it normal for girl to orgasm while watching gay porn?

Hi. I'm a quite normal and attractive girl, I also have a boyfriend whom I love very much.
But I have this odd habit of watching gay porn and enjoying it. I enjoy watching gay orgies. I love seeing a big hairy guy choking on an other guys penis.
My best orgasms.were while watching gay porn. Is that normal?
Should I say.this to my bf?
Are there any other girls doing it?
Thank you all ...
