I tried quite a few extra-marital affairs websites and there were only a few sites I really liked. I'd probably rank Ashleymadison as the best in this category (or maybe Saphrina, not really sure if I like it more or less cuz I found an affair partner on both sites but it seems to have less members). With a little patience you can find real women looking to hookup. Most are mssing passion at home and are desperately looking for some acknowledgement. Yes, there are some dubious contacts but ignore them and you'll be fine.
