After a recent bad experience, my wife went through a complete change of mood, she was moody, cranky, distant, irritable even in my presence she just refused to talk about anything sexual with me. I couldn't understand it; we'd been married for twenty years and cunnilingus and oral sex had always been one of her favorite things to do. My question was how come she was suddenly so angry and defensive? And why did I suddenly feel like I'd made a mistake in letting her have that little titty session before bed? Luckily I remembered a little video from Prague a few years ago which explained exactly what to do..
