bisexuality a cliche? and do i want it?

this will have to be the most nervous post i've done.
okay i know i said earlier that i was candid about my self and particularly about my sexuality. but i didn't state what it is (well i did but not clearly) although i have never been ashamed or nothing i just have been careful with who knows. since it dosnt only affect me. but my family and i mean extended family.
anyways
back looong time ago when i was 18. most of my discussions with my friends and Adrian (new boy friend) were about sex. threesomes were also a big topic of converstation. and being girls my friends and i found it comfortable to say what chicks were hot and not. (unlike guys, girls can do this and still maintain that they are 100% straight.) threesomes also became a huge topic in Adrian's and and i relationship. around this time i suddenly realised that i was more than just curious about sex with girls. i really wanted to do it. and had developed "crushes" on some of my friends (i say crushes but it really was just wanting have sex with them. i began bringing up 3somes with Adrian more and more and eventually i came to the conclusion i was bisexual.
bisexuality is a big scope so i felt the need to define it to myself. i was in love with Adrian and wanted to marry him (by this stage we were engaged) and loved men. but was also interested in women, and found them hot too. i had no desire to pursue a relationship with a women. and my feelings for women were basically all about sex.
admitting it was a bit scary as when i was younger i was always confused by the bisexual person. how do they stay faithful? do they eventually choose an orientation? how is that fair for their partner?
now i realise you stay faithful to your partner because you want to and its not that hard if you love them. no i didn't eventually "become" straight because i'm married. i still have the same feelings just i wont be having relationships now with women as im in a committed relationship. when your straight and you get married you still find other men hot, you just dont go and sleep with them. how is this fair for Adrian? i hope he has nothing to worry about me running off with another person woman or man.
after i said to myself "Lisa your bi!" i told Adrian he was pretty cool about it (guys dream and all that) and i think he knew. i then told my friends who also were "yep we know!"
it became a big thing for me. i wanted to experiment. and it was a big focus of my sex life and personality for some time.
now years later it has faded into the back ground. more people know now, like my mum and sister who i was afraid to initially tell. I've done my experimenting although i would like more.
I've reevaluated what bi means to me, i think if i was bi before i met Adrian would i'v had a relationship with a women?, if Adrian and i divorced would i go on to be with a women? i dont know these answers and i never will. and it dosnt really bother me.
i once thought everyone was bisexuality just on different scales.
and now in this age maybe im right.
to me bisexuality , especially for women has become a cliche. or experimenting with girls for young women has become a right of passage every one does these days (god i sound old) it seams every where i turn there is a bunch of young women kissing each other, saying they're bi. and i have to wonder are they? or are they just making a statement? trying to turn guys on? it certainly more acceptable now so is that why there is more women being vocal about it?
but it all seams cliche! and whilst im not saying im not bi anymore (its not a choice) i just hate being part of that cliche!
