That's what i found according to the acoustic version, but i am not sure about the lyrics.

Intro
A  C#m7  F#m X2


F#m     A
How can I deny this feeling?
C#m7
Can't use the fuse that lights the spark
F#m              A                 C#m7
Don't think i'll hold out too much longer
F#m           A
The lines are blurred in the dividing
C#m7
I deserve light, I desire dark
F#m       A               C#m7
Your influence is getting stronger
F#m                               C#m
Despite by mind, my body is still curious
   D                                 C#m7   Cm7
So won't you show me all there is to know?


A                  C#m7
I know I shouldn't call
                       F#m
But something makes me crave the heat
A            C#m7  F#m
Your love is bittersweet (so here I am)
A                C#m7
The fire in your touch
                 F#m
I always find so hard to beat
     A       C#m7  F#m
Your love is bittersweet (so here I am)


F#m         A
No substitute for real pleasure
C#m7
You feed the need that lies in me
F#m          A              C#m7
I've lost all sense to this devotion
F#m                                  C#m
One touch and there's a rush of electricity
D                                    C#m7   Cm7
So won't you show me all there is to know?


A                  C#m7
I know I shouldn't call
                       F#m
But something makes me crave the heat
A            C#m7  F#m
Your love is bittersweet (so here I am)
A                C#m7
The fire in your touch
                 F#m
I always find so hard to beat
     A       C#m7  F#m
Your love is bittersweet (so here I am)


F#m                                        A                
Bittersweet bittersweet but here i am your love
A                                            D
Bitter Bitter bittersweet but here i am your love
D                 Bm               F#m
Bittersweet bittersweet but here i am
F#m
Anytime you call my name


A                  C#m7
I know I shouldn't call
                       F#m
But something makes me crave the heat
A            C#m7  F#m
Your love is bittersweet (so here I am)
A                C#m7
The fire in your touch
                 F#m
I always find so hard to beat
