Generally an activity for the more experienced sexual adventurer, sounding is the act of sliding a (very well lubricated) rod down the urethra – the bit of your anatomy that you pee out of – for pleasure.
And strange as it may seem, plenty of people do just that and it’s more popular than you might imagine. Inserting something into your tender bits sounds ouchy, but plenty of people get off on it.
And yes, women do it too. But this particular fetish isn’t straightforward you need to do your research first and take care all the way. This is made simpler for men by the fact that the entrance is obvious and the internal tube is straighter and longer.
Women’s urethras are far more discreetly tucked away so even greater care needs to be taken to avoid damaging the delicate tissue.
Psychologically, many people find the fact that they’re doing something ‘unnatural’ a turn on. For people with a penis who so often tend to be the penetrators, rather than the penetrated – to have something inserted into their genitals is a complete headf***. In a good way.
