Vasectomy - done. Hot sex w/ no chance of unexpected pregnancy? Ya...that is a little ways off.
I have had a lot of dental work done. One of my incisors was chipped cleanly in half during a bicycling accident. It has been about a day since the procedure and this was less painful then, say, getting a filling. You walk in, walk out, stay off your feet as much as possible for a couple days. No heavy lifting/sex for a week. Of course, it is theoretically 3 months or 15-20 ejaculations before you're seaman is sperm free. Now my dear wife is indicating we can get the latter done in an embarrassingly short amount of time. All I can say is I'm looking under the microscope if they let me. I want to be sure.
