When two people believe in not having sex until after marriage so settle for sharing a banana... the woman peels the top of the banana. the man then thrusts the banana so that the skin wraps over his penis and the banana goes into the women's front bum therefore replicating sex.
Man: I want a banana.
Woman: go get one then!
Man: If i do will you share it with me?
Woman: ... I don't like bananas ...

Man: I never said eat it! I just said share it...
Woman: No! I am not trying that again! It took me weeks to remove the Banana from my front bum last time... stupid idea of 'Banana sex'
Man: Pleeeeaaaase?
Woman: ... fine...

Banana Sex is when a male and a female are about to have intercourse and the male doesn't want to 'stick his penis up in it' so he grabs a banana before heading in to 'do the nasty' and lays her on her back, both have their pants off, while he slides the banana in her. Then he has one of two options;

1] Continue till she orgasms. Then leaves it in her and runs.

2] Get up and run, after shoving it in her.

Banana sex is a mean gesture, usually done to embarrass women.
"Dude, i just had banana sex with that chick."
