Some years ago, when Craigslist still did personals (yes, that long ago) I posted a personals ad for anyone who wanted to get pregnant the old fashioned way. To my surprise, several replies popped up, some from obvious catfish or fakes, but one that sounded serious.

We agreed to meet for a coffee and things went well - an attractive woman in her early thirties with her own career and place in London's Docklands development, fairly upmarket.

We went back to her place, opened a bottle of champagne and set to work, a most enjoyable activity.

Every month I'd get an email telling me when she was ovulating and we'd do the same, often two or three days in succession.

After five months I got an email which was just a picture of a positive pregnancy test, and she deleted her gmail account. I'm not a stalker so I didn't go round to where she lived - I hoped I might get a follow up email, but never did.

So for those who find the idea hot, yes, it can happen and could even happen to you! I still get hot when I think back to that time.
