Testosterone decreases sharply after ejaculation, and it takes 2 to 3 days to rise up again. So I am not surprised that hormonal changes could affect how a person feels about their orientation.
I notice my sexual desire peaks at night of day and two after O. Which is an issue. Because a second O within the 3 days of an O hits very hard, and for up to 7 to 10 days. 10 days if it happens on day 2. However I do not attribute this peak to testosterone. I think it has to do with wanting to feel good. I think it is related to inflammation caused lack of irrigation on the brain. When I take Kyollic Aged Garlic I feel my brain relax and be happy and emotions stabilize quickly. Calm dawns! What a feeling. I think the better irrigation causes the brain to work properly in all aspects. Like neurotransmitter balance, hormonal control, etc. However I noticed that on days 1 to 3 after O one drop alone might be enough. There have been times that 2 drops on day 1 after O caused significant vasodilation. Which went away in 2 hours. But it is very unpleasant. Rapid heartbeat, have to lay down, etc. So when I take Kyolic Aged Garlic I start with one drop first, wait one hour, then see if I want to increase. Also I carefully mind what day after O I am. Since sensitivity to this supplement for me is largely increased on day 1 to 3. I am still figuring this out. But what was amazing was one day when I slowly increased to 10 drops I felt so well emotionally and mentally. But 2 drops can also cause the same effect in some days. So I think we may suffer from lack of micro irrigation, possibly caused by immune activation.
There is a recent article that explains how people with CFS for example have an immune mediated lack of blood irrigation. I think that is happening in POIS as well.
This is a very key article. Please take some time to read it. It could explain why so Niacin, Garlic, Arginine work for POIS and CFS, and why other immune response mediators also help both.
