Your comment suggests repentance of sin is meaningless.
If this is what you meant to say, it’s a lie.
Well, I just assume that if a guy has been a homo in the past, it’s because he has perverted desires to have sex with other men. And, if a guy has perverted desires to have sex with other men, a normal woman shouldn’t believe that his perverted desires have somehow magically evaporated or that he will never act in accordance with his perverted desires. A normal woman shouldn’t trust him.
