Can a homosexual turn straight?

Can a gay person become straight? What would it take for them to become straight? Has anyone ever heard of any instances in which a gay person turned hetero and lived happily ever after?  My home girl said they can pray about it and it can happen but i told her that I doubt it. If at one point you were attracted to men your not gonna just turn that off cause you prayed about it.  I don't give a fuck what anyone says that shit is not irreversible.  IJS  You can't just change your sexual preference.  I think that's why a lot of there Priests/pastors/bishops etc.... are coming out of the wood works cause obviously prayer didn't work and the flesh was weak(and I understand, LOL!!)  Please respond....
