Just thought I'd relay something of a horror story in the hope it might save other gentle readers (and their wives) a similar experience....
A while ago, a gentleman from France posted a message looking for 70's Britfilms. he and I corresponded about my sizeable collection (oh go on, make up your own jokes then....), as a result of which I arranged to meet him in Paris to do a swap for some of his 70's French collection. He did not turn up at the rendezvous.
To avoid my trip being totally wasted, I took a stroll that evening down the famed Rue St. Denis. When I was last there (in the late 80s) there were working girls shoulder to shoulder all along the street. Must have been hundres of them, ranging from about 10 (I kid you not) to maybe 60. Now, there are no more than 30 - 40, nearly all of the young ones are African (about 2/3rds of the total), and most of the rest in their 40s and older.
I paid a visit to a strip parlour, paying E30 to ogle the charms of a very pretty half French half Thai girl, who very promptly offered to have sex with me for E230(!) which I negotiated down to E100. She went away with my money and returned probably 15 mins later to ask for a tip. She was very persistent and in the end (staring at her beautiful breasts) I agreed. She disappeared for another 15mins, and on returning, asked me if my sperm was acid or alkali! Never been asked that before! All a con of course, as she then demanded I deposit a sample in her navel so she could test, after which I would be allowed to have my wicked way with her. Not being as young and frisky as I once was, I knew that after leaving my deposit, I would be unlikely to meet the full balance within a reasonable time. I declined to wank over her (how humiliating) and left minus E130.
Caveat emptor, sure, but a smart con which others might want to watch out for.
