perhaps the most *useful* way of thinking of this issue was articulated by the board, however the fact probably remains that unless being well endowed is negatively correllated to other significantly desirable traits, and we assume a large penis is something the vast majority of women would consider desirable (though there is certainly a range of opinions on just how desirable it would be) then we would find women are probably more loyal to men with larger penises than those who don't have them because loyalty is a function of the desirable characteristics of a partner (and obviously not merely physical ones) one final note: if this is a fact, it is probably utterly useless in one's personal life and is probably only noticable as a general trend... it makes more sense to focus on characteristics which you might have more control over like honesty or the amount of oral sex you perform for your partner....
