Russians do bathhouse/sauna deals without sex (most of the time). In Russian culture, bathhouses/saunas are a very traditional safe place for a group of same-sex friends to socialize and get drunk together. And naturally a lot of unofficial political and business discussion happens in saunas too.
And after a proper session in a Russian-style sauna one is totally exhausted to even think about sex.
Surely there are stories about businesses booking saunas for private events with hookers to bribe officials, but in most cases these are urban legends.
