I'm afraid of dating, especially lesbians because i'm bi and because i don't know where to find anybody?

do all women who ID as lesbian hate bis? i'm truly bisexual, i know this for a fact and its not a phase(been this way since puberty). i'm also extremely monogamous, one person type of girl is who i am. i don't feel the need to be with both, the person i'm with over rides everybody else(which is pretty much the same for everybody no matter what orientation they are). will i still be attracted to others yes, but i don't understand why people wouldn't want to be monogamous with me or date me. i would really like to be in a relationship with a woman because i've never been intimate with a woman(one time five minute long session with a guy who took my virginity, also kissed two guys my whole entire life but have never a woman so i know how awesome it is to make out with dudes) i'm eager to know how awesome it is to be with a woman and have a relationship with one(though i've never had a relationship with either). i have no gaydar at all, so i'm afraid that if i go up to a cute girl, she will actually be straight and scold me. i'm just very much afraid!
