May is Masturbation Month

Hooray it's come round again! Although I do wonder whether, being the Hound I am, I shouldn't instead be humping things and sniffing crotches. Blush.
Incidentally, since I aim to be educational as well as entertaining, I would like to point out that there are photos of different wanking techniques on Wikipedia. Don't thank me, it's all part of the service.
Enjoy!
