RBBSA is a type of "bisexuallity" were you find physical attraction to both genders but only sexual attraction to the same gender, often you will prefer to go out with the same gender but could happily go out with the opposite (although opposite probably wont work out as well). You only have sexual desire for the same gender so the thought of sex with the opposite one is not wanted.
In short you can happily date both gender but can only have sex or sexual touching (not involving kissing) with the same gender
