had it done about 15 years ago, no regrets.
no problems, local jab around the boys, bit of juice into the arm to relax me.
it relaxed me alright, i fell asleep! (had been working for about 28 days straight and was very tired)
was at work the next day, wearing 2 pairs of undies as recommended.
had to abstain for about 10 days, the first time after, i was a bit apprehensive (and full) but all was good.
after a few weeks i had managed to expel all the remaining swimmers, and some work with a dumb-bell on my left arm managed to even the muscle tones up.
i still have 1 spare dumb-bell if you are interested <they only sell them in pairs>[/
Hehe 1 spare dumb bell, thats funny stuff Dan
