I got work up the ying yang
When you begin to have intercourse with every intention of using a condom, however you start off without one. At some point you say to yourself *im going to get the condom*, but you never do. In her moisture, the sensation is so good, you never bother to get up and get one, therefore remaining raw. Short term; going raw, no protection.
