I once booked a massage from a lady on craigslist. 'cute 40 year old, massage for 3,000 yen'. I had little money at the time and it seemed like a good deal. This was about ten years ago.
Anyway, she shows up at my place. Was probably about 50, anorexic, wearing the weirdest outfit. looked like Skeletor a bit. Weird mannerisms, just something totally off about her. her 'massage' was mighty rubbing my back with vaseline, whilst every 5 mins getting up off the bed and walking around in circles like she lost something. She kept telling me how cool I was and she wanted me to come to an international party she organized.
On the flip, like the dog I am despite her already mentioned looks and age, I got a hard on and she gave me HJ at no extra cost. Was a weird experience. I think she just liked getting out the house and giving hand jobs.
Thats my impression of Craigslist. That and trying to sell anything second hand you have to deal with people that cannot read descriptions or loo at photos. For example you can sell a red sofa, with full sizes listed and a photo, you will be sure to get 20 emails asking 'what color is it?' 'how wide is it?'
