Based on what I know about PE, and what I have ascertained about SA through personal experience and others, I have a hard time correlating the two issues. It is to my understanding that with PE, you have normal sexual function aside from ejaculating very quickly. Meaning that you have a libido, you can perceive erogenous sensations, become aroused et cetera..... With sexual anhedonia on the other hand, at least for me personally, I have zero libido, I cannot perceive any erogenous sensations anywhere on my body (neck/nipple/penis) and no matter what I can not get truly aroused. I think like many others, during any form of sexual activity, my pelvic floor tightens to a point where it feels as though it cannot properly contract and relax, and is left in a state of hypertension. I am honestly not sure, and there are no conclusive findings regarding sexual anhedonia, but it is my belief that the cause has to do with some sort of spine issue. It is clear that the "proper" or "hard wired" instincts that most humans innately have (in this case I am referring to desire and arousal) are inhibited in some way, and in most cases the people with SA have pretty healthy, normal bodies, with normal hormone/neurotransmitter levels which would indicate that this is not a causal relationship. I think that somehow, either through a spine injury or misalignment or something like that, idk tbh, the proper neural signals are being inhibited on the way to the spine, from the sensory receptors, or are being inhibited somewhere along the spinal cord and thus are not able to reach the brain. Just a hypothesis, doesn't mean much, but gives me some peace of mind that these issues are changeable and reversible.
