You're in luck. I can tell you all about it. I just had it done about 6 weeks ago. No problem. It doesn't hurt much. The worst is when the doc pulls the vas out through the incision. At that point you will feel a tugging that is quite uncomfortable. He'll do that twice--once on each side. You'll have the feeling like you were kicked in the balls, but you'll get over it soon enough. At a certain point in the procedure I began to have a case of the cold sweats, but the wife was there to mop my face with a cold rag and to hold my hand.
My doc said he's had guys make a call in the middle of the surgery. They usually call a friend and say, "Hey dude, you'll never guess what I'm doing right now!"
My doc also advised me to drink a few margaritas before coming in--just as a little something to take the edge off.
My balls were really swollen. And black and blue. But within two weeks they were back to normal--still really swollen and black and blue. (the last part is a joke).
Also, I regularly shave my balls, and I did it the night before. The doc said it wasn't necessary. Although he said I had done quite a good job.
