The average guy could spend the day inhaling chicken wings and still want sex when he gets home. But if women eat too much - or are a little bloated or pimply or feel crappy for any other reason - they often shut down their sex drive. The reason? 'Females have this notion that they don't deserve sex unless they look and feel absolutely perfect, but that's total nonsense,' says Cynthia Gentry, author of What Men Really Want in Bed (Quiver). Your guy often picks up on your feeling like you 'shouldn't' have sex and is less inclined to ask for it, which only reinforces your thinking that you're not doable. The result is a lot less sex for everyone involved. The truth is, once your clothes come off, this is the extent of what a guy is thinking: 'Boobs!' In other words, he's not noticing that you have a zit or haven't washed your hair. So instead of closing yourself off, think like a guy and go for it anyway. A quick way to get out of your own head: 'Get him hard - literally. Reach over and touch his penis to let him know you want sex,' says Dr Patricia Taylor, author of Expanded Orgasm: Soar to Ecstasy at Your Lover's Every Touch (Sourcebooks Casablanca). 'When you see how aroused he gets, you'll realise there's no point in worrying about all that other stuff.'
