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