Join the club, I just came out of the same length relationship 2 months ago and i've spent many hours alone with rosy palm and her 5 sisters. Its getting less now but you need the release.
Are you thinking about the sex you used to have with your ex? I certainly do. makes it more furious but what the fuck, lets off the steam!
I was also worried that i'd become a serial wanker, but like the song by Ivor Biggun "it does me good like it bloody well should... I'm a wanker, I'm a wanker, and i'm always pulling my hood!"
