Not entirely separate.
The majority men who sign up at Ashley Madison are unlikely to be naive enough to imagine that they will get a fling for free. But they don’t let the risk of getting caught stop them even if Internet arranged rendezvous are only a few steps up from street prostitutes and escort services in terms of confidentiality.
Women who have affairs want to know what they are getting. Few of them will be on a. Internet site because they can’t see what they are getting.
And women who don’t want to get caught absolutely aren’t going to be giving up a credit card number, or logging on from a computer that they are known to have access to.
On the other hand, if a woman looking, she can easily find a man in her social circle, so why go the Internet route?
This simply reflects the promiscuity of men as compared to that of women. Even an old lady like me could find an affair in easy proximity, if she wanted to.
