i'm glad you decided to share..
i def consider myself 'queer', even though i'm married to the most awesome man...i identify closely with the struggle and politics of the lgbt movement, plus all my gay friends are just more fun and creative..
the point might be moot, since you're in a relationship with a guy at present, but i think it's sad you feel you can't live a 'free life' and maybe feel free to fall in love with a girl if your present relationship was to ever end. people can be very insensitive, and homophobic, especially when they don't know someone close to them in a same-sex relationship. this attitude might change if this loved one was to ever come out to them...
to illustrate: my mother straight out disowned me when i told her i had a girlfriend a few years ago (!). however she gradually came around and is now still friends with my ex...
i guess what i'm trying to say in this ramble is don't let hate and prejudice keep you from trying to attain happiness - with whatever gender. it's cliched but the ppl who truly love you will do so regardless, and if they don't, you are better off without them in your life...
