What am I ? And am I normal?

I know it's not easy to answer such question cause u don't know me in real but I'll try to give as much info about me as I can. I am simple girl live with family mom, dad & younger sis, I am 23 and I am at the beck of my life personally and professionally. My carrier is going great and I am doing well financially, personally it's little complicated I am bisexual though I like girls more than boys but every once and while I like to have fun with the real thing I have a GF that love me so much and I am crazy about her, that the head line of me. Now after an argue with my GF about my life style she say that bisexuality isn't real and I just going out with boy to satisfy my mother (my family know about my bisexuality since I was 16 and they support me especially my sis and dad) my mother want me to have kids the normal way and my GF see that I shouldn't do this and that I am not bi but lesbian and I am in denial. I do enjoy having sex with men from time to time and do love women and I admit more than men and I am deeply in love with her. But I lived my life free and wild Eisner I was 12 I developed early, I was 13 and have a B cup and I turn into a full D before Collage (thank good it's stopes there) and body was what you hour glass shape I am curvy I have a perfect *** flat tummy (I workout and swimming) I am curvy but tight. So I was hot and I know it, I lost my virginity when i was 15 my first girl-girl when I was 16, I told my family that I bi since then I lived the wild life I had sex with everyone ( not everyone everyone) when I see someone like I do. I did it all Boy-Girl Girl-Girl threesome (2boy, 2girl & boy-2girl) and even an orgy I even have a threesome that include my sis, weird I know but me and my sis are very close and we share a room so we very close. I used to bring boys home and girls and have sex and she just next bed I was so horny then (still now but I control t well) so we close and never shy from each other no matter what. As I said I know that I am hot and I think that body is perfect that why I love to show it I enjoy nudity beyond words so you can imagine that I love being naked at home( I used to be naked in my room all the time till I turned 16 I went public) my mom was mad even more than when I told her that I am bi but dad and sis told her that she home and she should be comfortable to be what she want, so I was living la Vida loca did all never regret anything. Now the part where I start to wonder about my life, after my fight with my GF I start to think about stuff I did if I was so driven by my hormones and thinking that because I have it I should use it that I heart others. Like when I have threesome with my sis is that okay my GF never commented about but know I think is that ok(we didn't do much with each other just kissing and touching nothing hardcore) and I teached my sis how to kiss is that ok too, being naked all the time at home and having sex with boy and girls in the same room we both did that. I don't know why I never thought about before but I love my sis and family and want them to be proud of me. I talked to my sis about and she said that I was the best sis ever and she love me and the way I dressed at school and college was sluty, I never wore a skirt that didn't show my panties if I wear any (yes I like going commando still do) my top all revealing my bikinis was not existing, now I am not like that still wear short skirts but not that shirt the proper length cause my job still like to show some cleavage all that I never give it another thought. I like to have a child the normal way meet a nice man have a baby and having him involve with my bBy life and at the same time I like my GF to be involve too I love her dearly but I am I suitable to be a mother or even a wife or friend some say that there is worse and that I am a nice person that care about other and friends but I maybe sexual but that part of I am. I don't know what to think I trust there opinion but I don't k ow any more I am lost for the first time in My life. Any advice or whatever you got to help and please no silly comment that a serious matter at least to me please
