Sex advice with Suzi Godson: My girlfriend gets red-faced when sex is mentioned

My girlfriend gets really embarrassed talking about sex. It means that if I ask her to do something a certain way, she gets offended and doesn’t want to have sex at all. What can I do?

One of the reasons so many couples struggle with sexual communication is because sex is understood to be a natural instinct and, therefore, we are expected to know how to do it. As children we get coaxed, coached and rewarded for learning to master basic human functions such as walking, talking and going to the toilet, yet when it comes to sex we have to figure it out by ourselves.
