That’s a completely different situation. Assuming that such a tape exists, the issue isn’t that Trump has sexual kinks. The issue is that the President is subject to blackmail from a foreign power.

If such a tape existed for anyone else and was in the hands of a foreign government, that person would not be able to get the lowest level of security clearance in the US because the opportunity for blackmail places them at great risk.

In an ideal world Americans would be more like the French and not care about people’s personal consensual sex lives at all, in which case the tape would lose all its blackmailing power, but since the American public does care, the possibility of blackmail is real.
