You are and will still be a "real man". Jesus. It's not like they actually de-nut you, they just clip a little cord and you're on your way. Take your pain pills and sit on some ice and you'll be fine. I have an ex who did it because he was sure he would never want to be a daddy (and later went into porn, but that's another story) and he was back on his bike in a week (much against doctor's orders, but that's the kind of guy he is). I was there. I saw the procedure. It was over in a couple minutes, and my guy was fine.
+1 what MickeyX said- once you crank through the swimmers still hangin' out, (I think that takes a few days, or a week, depending on how "active" you are?) you can go crazy and your wife will be able to totally enjoy it without having to worry about the pill working, the condom breaking, etc etc etc.
