dude, you need to get some action
I need a ______ (insert body part)
to get some _______ (insert body part)
I feel like __(having sex with)__ someone
Want to cuddle up with me?
sex talk focuses on the external act of "getting" something and objectifies what exactly is required to satisfy the sexual need, whereas sex talk focuses on the sexual state being experienced
More examples, anyone?
