Sorry this may only be relevant to the USA. I don't know if Ashley Madison operates in the UK but I did think it rather ironic and likely truthfully representative of male behaviour vs. female behaviour to learn that almost the entire user membership of this site is comprised of men. The last laugh being that the vast majority of these cheating men are not likely to find a woman to cheat with on this site after paying money to join!
