From a "safe sex" rather than a morality perspective, 1 and 3 are extremely dangerous if not performed by an intelligent person who is trained and experienced in how to do it safely. Especially 3. Quite a few people die every year.
Especially dangerous when theaw practices are combined with drug and/or alcohol use.
Whipping, if not extreme, is not particularly dangerous from a physical POV.
theaw = these.
Sorry.
