I can say with some experience that every women tastes different, some taste really strong and metallic almost, and others taste sweet. Also the time too orgasm can be different, Ive gone down on a girl that I swear only took a few minutes to reach orgasm, and came many times, and been with a girl that takes 15+ minutes to orgasm. Personally I wouldnt want to be with a girl that has too fake it. Of course she could be faking, not because she is trying to make you not feel bad, but because she is embarrsed that she is unable to reach orgasm at this point in her life.
