"I can't understand why more people aren't bisexual.
It would double your chances for a date on a Saturday night."
First goes a joke...
Masha or Misha (male and female names in Russia) - bisexual people don't care. Feels good, but not really. Gays don't accept them as "their kind', don't agree with the policy of "pleasing both'. Straight people don't see the difference between bisexuality and homosexuality as well.
And when it comes to literature, Russian hardly has any.
