Concerning Russian TV stations showing mature content, the answer is clear: none. As for Norway, this country does not allow hardcore mature content to be broadcast on TV. Only RenTV on Express 96 degrees East and DTV on Yamal 90 degrees East (both footprints do not cover Europe) show soft erotic in the evening, usually close to weekends. Nothing to be too excited about. One exception may be NTV+ on Eutelsat 36 degrees East that may broadcast Private Gold in Viaccess 2.5 (has to be checked). But you need an official subscription for this package and a BIG dish if you're watching from Central or Western Europe. So for the lucky ones, Hispasat is now much more attractive
NTV and (or) ORT on Sirius did show some hard-core mature content late at night some time ago. They may well still show, can't be bothered to stay up that long to find out, but as other members have said better options elsewhere.
