Hi Sally, and welcome;)
Your sexuality and feelings are absolutely normal. Christianity has it's roots in Judaism, which started as a desert tribe made up of men dominating women... how coincidental that their God just so happens to be ok with men marrying many women, invading other lands and forcibly taking their women, and death to anyone that would jeopardize that.
Your beliefs are also yours alone, and not to dictated to you and monitored by any organization. Please read up on JWFacts.com and learn the many things this religion has taught and tried to cover up. You'll be glad you did.
Don't you find it strange that the God of the bible would be ok with slavery, rape, genocide, infanticide, and testing imperfect humans but he's so bothered about who we fall in love with or who we have sex with? Humans that he created for no other purpose than to worship him?
I look forward to your future posts. Nobody on here will ever reject you for who you care for.
