If you’re nervous, they can knock you out for the procedure. You can’t drive yourself though. And not just any driver will do. They need to be responsible for you. So no taxis. I had nobody to help me out, so I went for local anesthesia.
I cracked jokes, which they said was a common coping mechanism for nervous guys. The nurses laughed, but the doc kept a straight face and steady hand. A couple tiny needle pokes were unpleasant, as was the tugging on the vas deferens, but neither particularly painful. Afterward I drove myself home to play video games and get high for a weekend. A bit of soreness for a couple days, but nothing compared to what she would have endured. I went back to work before recommended, and also masturbated too soon, but suffered no ill effects.
