I think my experience was pretty non typical, but ye, I did NOT have a good time.
Long story short, there was student in the room, so instead of just getting it over with as quickly as possible, my guy was EXCRUCIATINGLY slow to numb me, and not before he'd shown her how to enter the fucking konami code into my nutsack. At one point I actually sat up and asked just what the fuck he was doing, because I was in so much discomfort. It probably lasted 15 - 20 minutes total, but it felt like eternity.
Other than that, it was fine though. Felt like I'd been kicked in the nuts for a few days afterwards, but then it was all good. Still got a month to go before I get the all clear though.
