Hey 4thewind,
The mind is the most important factor in erections. There is no guarantee you’ll be 100% erect at ejaculation, either. You can ejaculate as low as 70% or so. Stress makes your unit soft, as does depression… But it does suck and will likely lead to more stress and therefore worse results.
That said, there are some factors you can check. First of all, People are reporting gains with as few as 50 jelqs per on day, so if your unit isn’t conditioned enough for more, take a step back. Go to 80 or 60 or even 40 jelqs and see what happens. Do you do kegels? A strong PC muscle makes it a lot easier to obtain a strong erection. Certain substances such as caffeine stimulate the active nervous system which also inhibits erections while promoting ejaculation (being stressed is the most common cause for both the limp dicker syndrome and premature ejaculation, often at the same time). I don’t know if you’re in shape, but if you’ve just come out of a bout of depression you may want to exercise since the majority of depressed don’t do that much. It’s good for mind and body. You can also take more rest days. Try 1 on 1 off or even take a week off and see what happens, isolate the problem.
I’m sure you’ve been told this, but if you’re struggling with depression and/or anxiety you should get that looked at too and not just for PE purposes. Personally I benefited greatly from power poses and stretching the m.pectoralis minor which is a small muscle in the shoulder joint. When it’s tight, it pulls your shoulders forward slumping them and causing pressure on your chest and anxiety. Stretching the muscle improved both my posture and my mood.
You’re likely just too stressed. That’s all. Low EQ is usually in the head. Then when you notice this, it gets worse. Hope that helps, good luck!
