Lyric discussion by StoriesinSongs.com 

The protagonist in this song is very mature.

He has understood that there are no external influences to blame for who they truly are.

So he's saying 'it's in the water' because water is one of the five elements. It's something very natural.

And when you feel bad for something that makes you You, you have to learn to accept yourself. Can't change who you are.

The song refers to the movie 'It’s in the Water' where a man blames his homosexuality on the water.

And that's ridiculous.

Being gay is part of him.

And in the song, the protagonist sees how depressed his loved one is by fighting to see the truth that he is gay, too.

All the pills he takes and the booze he drinks ('bag of golden brown') only support the assumption that he's homosexual. And all it leads up to is him and the protagonist.

The protagonist has already come clean with who he is, but his partner is still fighting, hence 'Bite the hand that feeds and tap the vein that bleeds' (emotionally) referring to the protagonist himself who is the one who suffers the more his partner resists the truth.

'Down on my bended knees' could refer to a blowjob and that the protagonist would do everything for the one he loves and he would even 'break the back of love' for him probably by that blow job position when he tries to show him how much he loves him.
