Every girl knows that they dictate when they're having sex by the new, matching underwear. If a boy doesn't notice this then it's infuriating for a few reasons. Firstly, you've spent a lot of time and money picking out new underwear for him. Obviously you wear it for yourself but you want to look sexy for him and it's an expensive look to get right. If he doesn't comment on them and tell you how gorgeous you are, then you'll feel a little neglected and it's silly because he obviously likes you enough to rip off your clothes, but you'd like him to actually say it. Finally, you're matching, and that's a big deal because you've already decided that you're going to have sex when you got ready earlier that day. This means that it's a special day because most of the time, you can never be bothered to find the matching panties that go with your bra.
