Title is OK. Better once I read through the first time.
Love your words,
Love the cadence...a tiny wee bit choppy in places, but absolutely minor, nothing to worry about,
beginning and ending are good.
If I knew what internal logic actually was, I would opine on it. But I do know that this poem is consistent in its message, as I perceive it, if that helps. The only word I would change is 'nostrils'. It does not fit. The word is too detached, out of place with the body of the poem, imo.

And to the theme:

I really enjoyed the dichotomy between love and obsession, passion and perversity, that you unfold in this, from sweet love to near sm/ pornographic obsession, all wrapped up in a mundane rainy day full of lust and love and the implied spiritual guilt.
Very male, to me.
Excellent poem, most excellent.

is that RTG got here first! Because he said everything I wanted to say about this one; and better! Damn you! Anyway, everything he said, I totally agree with, I love the progression of emotion from mere enamor, to full blown eroticism! Nice work! ~ Geezer.

is surely an uncommon stretch for me. Being a total atheist it's a bit hard for me to relate to any of the aspects of "sin" concerning any act of pleasure between consenting adults. But I do understand the hours of brainwashing having influence over people- I have had conversations with many Christians about this. There is even, for me, a deeply sadistic eroticism in so many of the Gothic crucifixion paintings.
The only thing I might suggest is to reinforce the rainy day in other parts of the poem, and make it a more important aspect of the narrative.

Thanks for the challenging offering!

As per my response to you in my poem, to continue the dialogue...
You have taken a lot of time with your comments and want to reciprocate.

First is the difference between "religion" and god. To me religion is a curse, and prayer a disease. Of course that is subject for a book with 300 pages. But I have often been on the side of Spinoza that god is the force that holds the universe together, the substance of all things. Our minds have corrupted it with myths and personifications. Another approach is that of Krishnamurti, suggesting that we use what we have to live fully and don't torture ourselves with silly questions like whether god is a male or a female or whatever, as we can never know this. Based on the sadistic world that a god may have created, in which all things struggle to survive and consume each other, and the brutality and greed of survival, as well as human history, I would repeat what someone scribbled on the wall of Auschwitz- "If there is a god, he would have to beg forgiveness from me"
But there is beauty in the world. And there is imagination. And I have always sided with Blake- God IS the imagination.
I am aware of instinct to create god, Freud and Jung. Yes, it is an instinct that developed as consciousness did over the hundreds of thousands of years of humanity. All I can try to do is focus that instinct on creating art, the imagination.

As to tantric systems- I have no problem with finding mystical completion through orgasm. The artifacts of history show that to be a constant theme, and seems to be a theme in some of your work.

You are a most unique person to be expressing yourself in these terms, as you have told me we are about the same age. There are times I remember the Greek philosopher who praised his old age because he could finally think straight, without the constant need to guided by his penis. (like George's Brain on that Seinfeld episode) . I'm not there yet, but I can sometimes understand it now...
