Are you born that way or is gender fluid?

Let me guess, you're going to challenge me attraction and your assigned or 'wanna be' gender are different. How? If what you're attracted to also assigns your non-biological gender? Yet if gender is fluid, why would it be wrong to change to a walk with Christ and learn to be attracted to the true opposite sex? Oh, wait but you weren't BORN that way, big gender is fluid? No... no, you can not have your cake and eat it too. You cannot have it both ways. I'm sorry.
