Help interpreting a sonnet?

Quick analysis help? What I see so far is that this is a woman who is scared to show her love outright, so she does it in the dark. I KNOW I am missing stuff. But can't seem to delve much further into it. Been on a weird poetry kick lately.I'd just like to make sure I am getting all the author is saying.

Thanks much for your help!!

"First Poem for You"

I like to touch your tattoos in complete

darkness, when I can鈥檛 see them. I鈥檓 sure of

where they are, know by heart the neat

lines of lightning pulsing just above

your nipple, can find, as if by instinct, the blue

swirls of water on your shoulder where a serpent

twists, facing a dragon. When I pull you

to me, taking you until we鈥檙e spent

and quiet on the sheets, I love to kiss

the pictures in your skin. They鈥檒l last until

you鈥檙e seared to ashes; whatever persists

or turns to pain between us, they will still

be there. Such permanence iis terrifying.

So I touch them in the dark; but touch them, trying.

its good, but i dont think it flows like a sonnet should. it should have iambic pantameter, going stressed, unstressed . . . five time in a line with the syllables!

She feels the connection with the tatoos, they are permanent and will always be there, even when the lovers are no longer together. She shares her love with his tatoos and they will never deny her, and will always hold her feelings. Just another thought.
