I am not qualified to answer your question, but if I may ask:  Why do you want to settle down to just one?

I mean, isn't more the merrier?

I suppose one answer I can give you is that when the right lover comes along who makes you uninterested in seeing anyone else, that will solve the problem by itself.

I doubt that there is any pill or practice that would do the trick, but I could be wrong.
