Fallback sex is the kind of sex you can easily negotiate to in lieu of intercourse. Generally its manual or oral or a combination of the two.
i always know that Keithwill be fine with a good hand job and a moment or two of oral sex..so i like to stay on top of my fallback sex techniques...its not as messy..
a girl that a guy will always go back to after he is done with his current infatuation. she gets labeled the fallback chick cause she will most likely take him back every time. she may or may not be aware that she is his fallback. she may think she's his main girl while he does his dirt behind her back. or he keeps her around so when females find out he's a dog he will still always have that one chick to show him love.
