HELP writing poem to BPD/SPD girlfriend on sexual chemistry!

Hey everyone, I am writing a poem to my ex/taking a break/almost back together gf who has BPD/SPD and depression. The poem is about our sexual chemistry - which is the best I have ever had in my entire life. Her as well. It's the one thing that got us started, kept us together and also brings us close enough to share our troubles - it's more than just sex. But it's hard to explain. I am late 40s she is early 40s if that matters. I do not have any significant psych disorders that I am aware of, but realize that everyone could have something if they really looked hard enough, or so it seems.

Can anyone here that is BPD, Schizoid PD, or depressed help convey what sexual or physical chemistry means to them? Anything that is NOT a cliche? I am looking for words or phrases. How it makes you feel, how important it is to you, what it feels like to have a truly once in a lifetime physical connection with someone. I am a pretty good writer, but poetry is a bit rusty to me. I am just looking for hints, ideas etc. I will tell her my pals on the forums helped me. I am just looking to break out of a bit of a writers block...something to start me off or fill in the blanks.

I will post the final poem here with acknowledgments. OR if you want to remain anonymous PM me please!! Anyone have a good line or 2?? A thought?Feeling? ANYTHING CATCHY and POWERFUL!!

Thanks a lot my friends!
