I don't know if I'm unusual, but my knackers were swollen and painful for around a week and a half afterwards, although the procedure itself was completely painless. Also experienced pain in the cobblers whenever aroused for about a year. All fine now though.
I had it done a few years back. Never felt a thing during the op. about a week of swelling and pain downstairs. Bruising lasted a few weeks. Bloody painful when feeling randy for about a year, but that went away.
