^This is the problem with "assisted" re-orientation. Self re-orientation has a good record of success because it's internally motivated. It doesn't take much to decide that rubbing a guys crap on your ding-dong isn't something to place at the center of your existence. The assisted proposition establishes that the patient can only do this with the help of others.
I'm sure the great majority of homosexuals who go in for that are consciously or subconsciously DETERMINED to sabotage the process. They desperately WANT to be able to point and say "See? SEE? it's IMPOSSIBLE!". It's the prospect of not finding a female to provide as much stimulation, being targeted by offended predator types and their nasty pals for re-assimilation, not being able to indulge their drama-queen impulses, unwillingness to deal with the expectations of females and SABOTAGE that produces the failure rate.
I'm sure that if you could take the homosexuals who have fallen deep into it but nonetheless sincerely desire, consciously and subconsiously, to escape and provide them with a moderately attractive girl friend who is guaranteed to provide all the stimulation they could hope to get from the homosexuals without any greater expectations, the success rate would SKYROCKET towards 100%. Persistant homosexuality is a function of the availability of stimulation and the degree of satisfaction derived from drama-queeny, rebellious, petulant behavior.
