All: about
this question (which I don't want to onebox in here), the personal aspect makes it rightly on hold now (thanks @Seth, @DoubleAA). My question is: if it were reworded to be (a) general (what are the relevant halachic sources for...) and (b) more modest (dominance-related sexual activities), would that be ok? Should we advise him to do that or just shut this down? I want to be modest but only as restrictive as we need to be. Thoughts?
