Is it normal i was more into women when i had a boyfriend?

When I had a boyfriend, we had sex a fair amount, and sometimes it was awesome and foreplay was cool (mainly when we were both drunk) but then a fair amount of the time, the sex wasn't great and it was mainly for him as I didn't want to be the type that rejected sex and wound up her man.

During that time, I'd sometimes fantasize about women (and men as well) while alone, and I'd only get off to women porn, and although I've always liked men and never had an appeal for women, I found them pretty appealing and one time drunkenly flirted a lot with a girl, which is something I'd never imagine doing.

He wasn't a typical manly guy, he was only an inch taller than me, had long hair for the first few months, I did like him with a beard but he was always a scruff and totally acknowledged feminine side and believed in gender fluidity - he still referred to himself as male. I totally accepted his point of view.

Now that we're broken up, girl porn has kind of lost its appeal, and I can't imagine wanting to try stuff with women any more, and I really like this one very bloke like male.

Is it normal I was only curious about women when in a relationship?
