Protect your erection. Wrap it in foil before checking her oil. A crank with armor will never harm her. If you really love her, wear a cover. Muzzle your snake.
Sex is cleaner with a packaged wiener.
If you can't shield your rocket, leave it in your pocket. No glove, No love. Don't be in such a jiffy, cover your stiffy. AIDS is no joke, be sure to wrap before you poke. Even though you're tired and sleepy, take the time to wrap your pee-pee.
