Yeah - I was never going to go a couple of weeks without wanking ;-)
Today's day 4. The occasional bleeding had stopped yesterday morning. I had a day out on the bike with no trouble - came home horny, wondering what would happen if I got a stiffy. And the answer - nothing - no pain / no blood. So then I started jacking off - really gently, with no great power - just stroking the shaft and not touching the head - and 10 minutes later I shot a huge load!!
God it felt good. It wasn't quite as amazing as I thought it would be... but there again, I wasn't touching the head at all as it's still very tender. Hopefully that'll happen once it's healed a little more.
