A lesbian can be in love with a woman and a gay can be in love with a man, what about bisexuals, a man cannot love two persons. If there is something like they are born that way, it just not gonna work for him, he cant marry a man and a women. Every human is born with sin nature in him; he just has to fight it, you can not fall into it. Anything other than not being straight is not normal, that’s my conclusion.
