Look how many women he has to deal with all the time. No man can put up with that. Even just one can be too much for most, if she's got a strong libido. And almost as if by design, a man who has a woman already is slightly more instinctively attractive to women, which goes up based on how many women are attached to him - because clearly he can provide in every way for each one, meaning he might be able to do so for 'you'. Instinct-wise, women are attracted to providers, it's the only way our species would come to exist, and having multiple women with him already proves his level of ability in providing for them.
