Karma Yeshe Gyaltsen wrote:The precepts are designed to guide our actions until we develop the insight to act in a wholesome way intrinsically.
Actions can be evaluated based upon the criteria : Do they further awareness?, Do they further Compassion? If they do then the follow up question is Do they lead to insight?
It is indeed possible that if the first two are present in so-called BDSM activities, then insight could occur. However that insight would shine a light on the unwholesome conditioning that lead to the activity in the first place, so, in that case the activity would be theraputic.
People rarely ask, or acknowledge, " How am I being masochistic in my daily activities?" "To what extent am I being self defeating?" (the irony of this is not lost on me from a Buddhist perspective)
I would propose that the Buddhist path is designed to lead us out of masochistic or self defeating mind states, and their accompanying activities.
If BDSM activities lead to this insight, then they are wholesome. If, however, they act to reinforce these tendencies, though pandering to unconscious mind states they become unwholesome.
I would venture that the vast majority of BSDM activities fall into the latter category.
I agree that the majority of activity's fall into the later catagory , I think its sad that such a rich arena for exploration is not used more often for the benifit of beings . Most people don't want to give up there kinks . All the meditation in the world is just wall papering over what needs to be dealt with but when you are willing to look and really see , thats when real and lasting peace can be found Yeshe



Nonetheless, I would suggest that deliberate abstinence by itself misses the point.
If one is seeking spiritual clarity, it might be helpful to abstain for the express purpose of obtaining a more detached perspective on sexual desires, just as with any other activity or practice one is engaged in. Taking a step back can have a centering effect and improve perspective. 
Regular sex is good enough.
