Whenever you realize you've banged someone, and you don't know why.

This usually occurs whenever you're intoxicated.

Kind of like "head on straight", only sexual.
Dude, why in the world would you fuck Jenna?
I don't know man, I didn't have my dick on straight.

Get the Dick on straight mug.
Sort of like "Get your shit together." Means you need to fix something or get better at doing something. Only complete thugs/ballers can use this without sounding gay.
Guy A: "damn dude, I can't figure out how to get our internet to work."
Guy B: "Well you need to get your dick straight."

Guy X: "Damn I just messed up three serves in a row"
Guy Y: "Get your dick straight, bro."
