That is because for younger males, and older married / divorce men, sex no longer sells.

Now I was raised that beer were for men and it was un-lady like for women to drink. So I am sure it is believed it is offensive to women that seeing a one-half naked, pretty female makes them feel beer is a mans drink.

Men drink beer and that is usually a womens partner. Plus it makes women feel bad about themselves drinking alone, so they are less like to buy beer too, which pack on pounds, but it is fine to feel a since of togetherness with her spouse, because she can't beat him, might as well join him . But when you can package beer that it is cool refreshing more about an good times then the market just opened up to all those lonely women. Beer is relatively cheap and has lost its sigma that it is mostly for men.

Women as a result are buying more liquor than ever. In fact there is an epidemic of alcoholic women over forty that has never been seen before. Uh, thank you beer marketing for freeing up us women into the beer drinking market. Maybe not so much.
