Cured? How do you cure it. Is there medicine for it? It's a preference, right? He could go back at any moment. He's such a character! True comedy.
Many men who are heterosexual experiment at some point with homosexuality, usually in their teens to their 20's. Some more so than others. I've met guys who have had sex with other men, nto because they are necessarily gay, but because it avoids pregnancy. Most bodies will respond to stimulation no matter what gender is involved. For those men it is more about just getting off.
In the end it isn't the gender you have sex with that determines your sexual orientation, so much as the gender whom you develop feeling of being "in love" with. For some it is only the opposite gender, for soem it is the saem gender, and there are also those who can develop such feelings for either gender.
As for the Filipno presdient... Taht he felt a need to declare what he said publicly to me indicates that he is probably more trign to convince himself then he is trying to convince others.
