Is it normal for girls/women to sometimes feel this way?

I am 17. I'm a female. I'm "single". I have never had an actual boyfriend, and I sometimes have these fantasies about what mine will be like when I finally find him. I sometimes wish that my future boyfriend is bi. Is that bad? I mean I fancy gay guys for some reason. I'm like obsessed with them. I even want to date them sometimes. But gay guys like guys. So the next best thing is a bi guy. But I kinda want him to be with me and also let me watch him with other guys. Am I a perv...or a "fag hag" (not trying to offend anyone but that was the only term I could think of for my situation)
