But a realist would have to ask uncomfortable questions like why such men were lonely and unhappy in the first place.
When a woman gets married and has children, her whole life changes. Her husband is no longer the focus of her life, her children are. She loses interest in sex, and doesn't see why she should have to do it any more. If she wants another child, sure, but otherwise not. To her, it's just one more person who wants something from her at the end of a long day at work, and this one she can actually say "no" to. So, she does.
Meanwhile, the husband, cut completely off from one source of sex he is allowed to have, grows increasingly desperate and unhappy. I don't condone cheating at all - but damn, marriage doesn't mean celibacy. Or, it shouldn't. This is the point at which feminists burst into the conversation shouting "RAPE!" (but they always do that) and that's not my argument at all. A wife *should* love her husband and *want* to have sex with him of her own free will. This isn't happening.
Nobody supports cheating men, but let's be honest here, men need to have sex in order to keep healthy and sane. A website that promises it to them for only $19.95 per month is going to get customers, plain and simple. Remember: desperate and unhappy. Human beings are capable of some pretty fucked-up actions when they become desperate enough. The fact that this website didn't even have any women to match the men to just makes them even more scumbags than we already knew.
