We’ve written before at HuffPost UK about what happens when an actor gets aroused during a sex scene. 

But we have another, more fundamental question: how do the medesty garments, or the little devices actors use to ensure thay’re not actually fully nude in naked scenes, stay on? 

After all, many of the pieces look really flimsy – and it’s not like they’ve got straps or waistbands to hold them in place. 

Luckily, intimacy co-ordinator Dr Jessica Steinrock shared an informative video on her TikTok page – and she’s not the only expert with helpful insights. 

How do modesty garments stay on during sex scenes? 

Well, it (obviously) depends on your anatomy and what you’re wearing. In her video, Dr Steinrock used three examples: the “classic modesty pouch” (also known as a cock sock), a strapless thong, and a combination padded pouch.

The modern modesty pouch is a newer model of a very old garment, she explained – it looks like a little drawstring bag. 

“Shaft and testicles go into the pouch, and then there’s a drawstring to kind of tighten everything up – not too tight!” she shared. Some newer versions also have a small rectangle at the top onto which tape can be attached for added security.

“We wouldn’t use just these for a scene of stimulated sex,” though, she continued, as it’s a bit flimsy.

For more security, a strapless thong – a kind of tapering triangle with a kind of whale tail shape at the end – can be used.
