Disgusted by my bisexual friend

A few weeks ago, I thought I was bisexual. I had another bisexual friend (we're both girls) who I actually broke up with my boyfriend for. When she kissed me, her breath smelled like what I picture dead babies to smell like. She is not very attractive and has a massive under bite. Because of her under bite, all she could do was basically rub her bottom lip against mine. I've been told I'm a very good kisser, so I was disturbed by this. I almost threw up on her by her lack of skill and the smell of her breath. We were alone in her room, and after I stared at her in shock, she sat on me and started dry humping me while kissing me. That morning, I basically scurried out of her house, never to return or talk to her again. Now I feel nauseous and disgusted by her whenever I see a picture of her, and no longer consider myself bisexual. She basically scared me out of bisexuality. Now, I can't stop trying to get attention from males (I'm receiving it aplenty, though!) after her. I've never been this way before. Is this normal?
