a: because to a certain extent it is true. how many women do you know who enter relationships regardless of the fact that they might not be strongly attracted physically to their partner, and how many men? i used to think that the sex drive was more or less equal across genders, but i've really come to the conclusion that sex is way more important for guys (also where the production of endorphins is concerned, ie men are made happier by sex than women are, in general).
q: am i right?
