Your story is inspirational and relatable for many. I too am bi...but, unlike you never had the confidence to explore in my late teens and twenties. Wish I had, but can't unwind time. It wasn't until I was in my 30s I accepted myself as bi and even then not openly. So, I admire you completely. God doesn't judge you as your family wants you to believe...your family are sinners too (we all are), so they shouldn't judge you if they believe you being bi is a sin (which is it not). God accepts those who show grace, humility and love to others and God doesn't want you to live in fear of Him or His perceived consequences. Be yourself, enjoy the sexual preference God gifted you, and forgive your family for their own shortcomings. I wish I had a roommate like Jake to give me the courage I lacked then...and I would have likely been jumping his bones and pleasuring his tool, body, etc. daily (as I hope your story soon reveals).
Final point, I think being bi may be the hardest...one day you want pussy and nice tits and the next the cock and hot, tight ass of a dude...some days both.... On the other hand, it keeps things exciting.
