When having to deficate really bad, have your lover press their tongue between your butt cheeks, then trying to see how many times you can release and pull in the turd before pinching it off in their mouth.

Someone that always Snapchats a video with a long time duration.

Plain and simply a vagina

A sweet sex position only the advanced can conquer.

A totally straight, not gay poor man who wants to become a woman acquires a local prostitute and pays her to give him oral sex...
in the midst of it when both his scrotum and testes are on her mouth he knees her in the chin and thus severing his genitalia, leaving a bloody hole(I.e. a vagina).

It’s like doggy style, except you place your partners head close to the wall or headboard and push them gently against it until their head pushes into their shoulders. Then pull them towards you and thrust into them fiercely so their heads pop out like a snapping turtle then repeat the process as necessary.

When a man's penis hits the far edge of a females clitoris, it makes a loud flesh-to-flesh noise similar to that of a snapping turtle.
