Y'know I'm gonna knock this down a few pegs:
Leviticus
This book... is the worst possible thing you can draw a conclusion from. Leviticus also considers wearing mixed fabrics a sin and planting more than one kind of seed in a field:
"Do not plant your field with two kinds of seed. Do not wear clothing woven of two kinds of material."
-- Leviticus 19:19
Getting a shave is a sin:
"Do not cut the hair at the sides of your head or clip off the edges of your beard."
-- Leviticus 19:27
Eating any form of fat that comes from meat:
"'This is a lasting ordinance for the generations to come, wherever you live: You must not eat any fat or any blood."
-- Leviticus 3:17
So yeah... That book is not to be taken seriously
Corinthians
The original translation does not use the term homosexuals or sodomites... at all. It uses the terms: Malakoi and Arsenokoitai. Now, let's look over how the terms for Malakoi(Or Malakos, it's singular formulation) were used by Jesus?
"But what went ye out for to see? A man clothed in soft raiment? Behold, they that wear soft clothing are in king’s houses."
-- Matthew 11:8
"But what went ye out for to see? A man clothed in soft raiment? Behold, they which are gorgeously apparelled, and live delicately, are in king’s houses."
-- Luke 7:25
The bolded parts were referred to as Malakoi(or malakos), so that means having an easy, soft, luxurious life where you can do what you want with no consequences and never having to work or sacrifice anything. A loose translation can lead to lust as well, but not neccessarily same-sex lust. The second term(Arsenokoitai) is usually used to describe falsely taking(or would you prefer stealing?) something hence why you see it says "thieves" after it says "homosexuals" in the "modern" draft of the Corinthians not sodomites:
"Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor homosexuals, nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God."
-- Corinthians 6:9
The verse also believes fornicating is a sin, so now I guess over 75% of the population should burn in hell?
Romans
You should realize a bit of context. At the time, the actual translation meant a man leaving his wife to have sex with a peasent(usually a male boy); this was more referring to pedophilia and adultery on the sickest level than homosexuality.
Timothy
Once again, the term used was Arsenokoitai, which at the time meant thief. In newer eras it and Malakoi referred loosely to lust, but that's out-of-context applications to the text.
So far, the holy scripture does not directly suggest homosexuality is a sin(other than one or two books that suggest 99% of living in any era is a sin).
The Blood of Jesus Christ (the Lamb of God Who takes away the sin of the world) will redeem, deliver, save, wash, and rescue you if you don't want to be a homosexual anymore.
No offense, but this is stupid. If God didn't want me to be a bisexual, he wouldn't have allowed me to be born as such(and yes, it's scientifically proven people are born like this). And no, you can't say "Well God doesn't want you to murder/steal/cheat on someone but you do" because that's a life choice and nobody's born a murderer, but rather they are a victim of circumstance created by other people. Sinners are made, not born.
So I don't think Jesus would want me to apologize for either having a girlfriend or a boyfriend, instead I'd think he'd want me to thank him(and I do) for allowing me to live a happy life with another person who loves, cherishes and respects me... As all human beings should do.
