Anyone knows where to buy this underwear/lingerie piece for men ?

[Spleen.]

Hello,

I am looking for the piece the guy is wearing in this video but can not find anything similar online.
Oral_Tantric_Expert | This cute Russian 25 y/o was very interested in giving it a try in the tantric massage as his first time was gorgeous.. He e en asked me when could we have the next session

Does anyone knows where to find such type of underwear/lingerie ?

Thanks!

The strings on the left of the picture indicate to me that it is sold as a ladies one. Nothing wrong with looking there.
