if your female significant other asks you to buy any of these products:
panty liners or pads
a lady shaver
don't trip on it.
don't think about it.
just do it.
you're not the first guy to be saddled with this and you won't be the last. there's even a chance that your significant other will actually give birth to your child - a boy maybe - who will probably be asked to do the same thing in the future.
so, suck it up. you can always pick up a playboy or a penthouse or a maxim on the way to the register and hide the aforementioned items.
