Q. Can you tell me why, when I am ready to climax, I pass wind? I hate it and don't know what's causing it or how to stop it. Any ideas please?

A. I wonder if you’re talking about actually passing wind, or if you mean a queef - which is the odourless trapped air that can escape from your vagina during sex? Rest assured that although it sounds embarrassing, it’s quite normal!

You say it happens when you’re about to climax, and I suspect this is because that’s the moment when you’re completely letting go. Try avoiding doggie position for intercourse, or having your legs in the air, as these tend to let air into the vagina. Your partner should also avoid pulling right out and then thrusting deeply, for the same reason.

But if it is anal gas you mean, then steer clear of spicy or high-fibre foods that cause flatulence, along with carbonated drinks and chewing gum. Reduce the amount of fat in your diet, eat slowly so you don’t swallow too much air and try to go to the loo regularly - especially before making love.

It’s also worth running this by your GP, in case you may be suffering from a common condition called IBS (Irritable Bowel Syndrome). Your doctor will also be able to advise you on the best tablets/medication for reducing wind.
