Are there any therapy clinics or retreats that help straight people be gay?

Can anyone point out an instance where straight people entered some type of therapy to be gay? This is about twice now that Nightline had a segment on some treatment or therapy that some gay people use to try not to be gay, be it clinics that treat the suppose SSAD, a retreat program like ”Journey Into Manhood” that suppose to offer Ex-gay Reparative Therapy. That got me to wondering if there was an opposite of that for straight people who want help being gay, a OSAD of sorts?
