Is it normal to be bi curious?

....so I'm just alittle bi curious

okay so im 20 years old and for the past few years i have watched a lot of porn. I have been going out with my boyfriend for abotu 6 months and he finds it extremely hot that i watch porn. After watching many different typs of porn, i have to say lesbian porn is my favorite. Yes i am a female but watching girl or girl is so much more sexual and romantic rather then agressive. My boyfriend thought this was hot too. I mean come on a girlfriend who enjoys lesbian porn? he thought i was so kinky. so anyway, lesbian porn started to become the only type i would watch. I was okay with this, but then i started having this wierd urge. I would fantasize about some female porn star(when i wasnt watching porn) and then it hit me...im alittle curious as to what it would be like to do something with a girl. Again my boyfriend thought this was really hot. he asked if this meant i could bring another girl into the room with us. heres what i think: If i was really drunk or high and I didnt have to do anything to the girl, then sure. I am bi curious but, I can not touch a girl or pleasure one. It freaks me out, but I would let a girl touch me and pleasure me. having it be done to me is the curious part. i have no intentions of pleasuring a girl its to wierd. okay i know this story is just one kinky mess, but i want to know if its normal for a 20 year old girl with a stable bf to have such curiousity in the same sex?
