goes both ways 

Has no preference for either sex, will have sex with either.

GayGuy1: "Mmmm, look at that sexy hunk of meat over there, I'd love to get deep inside of him. Too bad he has a girlfriend."
GayGuy2:"Take a chance bro, I know for a fact he goes both ways."

This Door Swings Both Ways 

'This Door Swings Both Ways' is a song written by Estelle Levitt and Don Thomas and performed by Herman's Hermits of Manchester, England. Surprisingly serious thoughts behind a cheery, light melody. Recorded in 1966.

lyrics:

Everyone's life is bittersweet
It's a door that opens wide
And no man can call himself complete
Till he's seen it from both sides

This door swings both ways
It's marked 'In' and 'Out'
Some days you'll want to cry
And some days you will shout

This door swings both ways
It goes back and forth
In comes a southern breeze
Or a cold wind from the north

This door swings both ways
Lets in joy and pain
In comes the morning sun
And then the evening rain

This door swings both ways
Lets in dark and light
Every day you make the choice
To let in wrong or right

When shadows fall
You must prepare yourself for sunshine
For everything there is an end
And so my friend you must be brave

This door swings both ways
Which one will it be
Will we live in happiness
Or dwell in misery

This door swings both ways
Lets in earth and sky
Make the most of livin'
If you're not prepared to die
Make the most of livin'
If you're not prepared to die

have it both ways 

to profit from two positions that are polar opposites

Contrary to popular belief, the powers that be can't have it both ways with drug laws.

Door swings both ways 

Defines a bi-sexual person, usually but not exclusively defines a male. Primary sexual preference is irrelevant, the determining factor is that singular fact: if the person is willing to have sex with men and women, their door swings both ways.

Woah, I just found out Eddie's door swings both ways! This is great dirt! This explains all the time he spends over at Oscar's apartment!
