Martin is trying very hard to conform and I wish him well with his struggle.
Tell him to get back to me in 15 years and swear on his bible that the 'cure' remains intact. I've already told you that I have been around long enough to see the efficacy of your 'cure'........and it isn't. Martin's desire to please you (plural) and his desire to be acceptable to his God have filled him with an enthusiasm to be straight. Once the passion has worn off he will find it increasingly difficult to maintain the charade (although he will be fervently convinced, at the moment, that he is 'cured').
Please DO NOT hire a prostitute to confirm his new found hetero status.................it will have a profoundly shocking effect upon him and may well undo your 'cure'............which whilst desirable, will be at the expense of his mental well-being.
Please try to see him as a human being rather than some sort of eugenics-like experiment.
