Is it a sin?

I don’t believe homosexuality is a sin.
God is about love, and love goes all ways!
Man + Man = Love.
Woman + Woman = Love.
Woman + Man = Love.

I am not heterosexual, I am bisexual, but I believe in God.
Many do actually believe that homosexuality is a sin, but please rethink.
What is god about? What is homosexuality about?
LOVE!

Why isn’t it a sin being heterosexual?
Why isn’t it a sin loving someone of the opposite sex?

That it’s not meant to be doesn’t work on me,
why would it happen if it was against god and his message of love?
Honestly I’d like to know, please tell me.
