look up any word, like donkey punch:
The time frame after a penis ejaculates during which the penis will remain soft because of the loss of semen that it has endured. Time length will vary by male.

The male whose penis has just ejaculated will usually want nothing to do with anything sexual until his semen level goes back to normal.
Because he just ejaculated, he's now on his retraction period and wants nothing to do with anything sexual.
