Can you be a gay christian?

I was atheist and agnostic for a while but i became Christian this year when i started to date my girlfriend. I didn't become christian cause i think theirs some bearded dude in the sky i just became it because i want to thank everything and i don't know how i got here or how my hands are moving but thank you. You'll start to appreciate life more and be more thankful. I still don't believe in anything the Bible says i just go with my gut and do the right thing and i think that's what determines who goes to "Heaven".
