"My last girlfriend was bi-sexual she liked girls and boys she called double dippin"

Some prefer androgynous partners, some don't. Some really love the differences between the sexes, others don't see those differences. Some bisexuals are only attracted to 5% of one gender, and 60% of the other - you don't need to be 50/50. And some bisexuals believe that thinking in terms of two genders is restrictive.

People think of bisexuality as transient because they don't understand the fluid nature of sexuality. At different points in their life, many people are attracted to different things and seeing the transitions as either "rebelling" or "settling down", as either "awakening" or "selling out" doesn't help recognize that all through your life everything is changing.

Some of us are in happy relationships with one partner, others have multiple relationships and some swap to dating the other sex whenever their current fling ends. Some bisexuals are happily married and raising children. Some bisexuals are single, some are celibate. You do not need to have ever have had sex to be bisexual.
