Backed up?

I chat often on Yahoo Messenger. I troll on several website looking for yahoo email address and randomly send IM in hopes they might be on at the same time.

One of the IMs I got back was from a old male. We've been chatting for a while now. Mostly x-rated stuff... about masturbation, his wife, our sex life. He knows I lived in Japan and like typical american men he asked whether I have gotten any from a japanese female. I have not and I haven't gotten any for a long time now. My right hand has kept me company. He was amazed I could last long without getting any and he said if it was him, he would have lept on the other side of the fence, so to speak.

So my question is... how long will you go celibate before you go crazy and jump on the other side of the fence?
