pull a u-turn
to bend your erect penis backwards, into a U-shape, for the purpose of fucking someone with just the shaft, explicitly not using the tip.
Sharon didn't want to play a game of just the tip because she "knew how that was going to end up," so I opted to pull a u-turn and gave her just the shaft instead.
