Hello Everyone, I am 31 now and I have maximum 60%-75% hard in any situation(with porn, morning wood(I am not sure about whether it is morning wood, when I wake up, my penis is totally soft, however, in maybe after 1 minute it start to erection and max 60% or 70% )----last about 1 minute) Now I may know why I do not have full 100% Erection during the daytime because my brain is hurt by porn or other strong sex stimulate so my brain cannot send enough signal to my artery so I got weak erection during the day. During the daytime, my erection is maximum 60% even with porn. (This is caused by PIED) About my weak morning wood, in recent two days: Day 1: I have weak morning wood(max 60% or 70%) (Actually, I do not know whether it is morning wood, when I wake up, my penis is totally soft, however, in maybe after 1 minute it start to erection and max 60% or 70%) (Lying down position)-----last about 1 minute Day 2: I have weak morning wood(max 60% or 75%)(Actually, I do not know whether it is morning wood, too, when I wake up, my penis is soft or a little bigger(not hard), however, in maybe after 1 minute it start to erection and max 60%(without compress my pelvic floor muscles) or 75%(with compress my pelvic floor muscles(Kegel exercise)(Lying down position)-------last 40 second to 1 minutes. When I stand up, the erection goes away in 5 seconds even if I compress my pelvic floor muscles(Kegel exercise) My questions: 1. Does your penis get harder when you compress your pelvic floor muscles(Kegel exercise)? 2. Does your penis get softer when you relax your pelvic floor muscles? 3. I read a topic about how penis gets erection. When big blood flow of arteries(because artery muscle relax) come to corpora cavernosa of penis, the corpora cavernosa will expand to compress veins around penis, so the blood flow of veins will limited.So erection happens, because the compressed veins trap the blood in corpora cavernosa of penis. Does it mean when erection occurs there is no blood flow in veins or there is still a little blood flow in vein and the little blood flow still drain from vein? 4. I am afraid that I have VL because I cannot get 100% full erection in any situation(Maybe In my teenager period, I had one but I forget. I am 31 now). At present, The maximum I can get is 60-75% hard of my penis. Anyone has the same situation with me? Is there any one who is professional about VL, weak morning wood? Please help me.. Sorry for the Bad english, because I am not native speaker, I almost search all information by using dictionary.
