I have been dealing with this issue for the last month or so where I will be masturbating for 5-10 minutes when all of a sudden I will start losing my erection. I have started to get nervous when I masturbate because I am now constantly expecting the ED. I have been having days where it isn't really noticeable and other days where I am masturbating and I will end up with a limp after 5 minutes.It starts to go down and sometimes I cum at 50% erection and I have came completely flaccid before(which leads me to think its biological) .When I get random erections/morning wood, the erection is only partially filled with blood and doesn't really go rock hard. I have tried cialis with OK success but it isn't a miracle pill either.What could possibly be going on here to cause such an awful thing to happen to me. My penis also seems shriveled up to about 2 inches and I have to masturbate it for 30 seconds before it gets hard(80-90% erection only to lose it 5 minutes). Sometimes I will start to lose it and it will randomly get hard again. I am not sure if it has to do with arousal level but even if arousal level dropped I don't feel like I should lose my erection in seconds. Could this possibly be a venous leak?
I used to be able to masturbate 1-2 hours without cumming,now I am lucky to get 10 minutes. I have asked for help on other forums where they believe in a nofap philosophy but I feel like I am talking to a wall half the time. All advice will be appreciated.
Edit:Forgot to add that I find it easier to keep an erection when I dont use KY to masturbate. I also cannot achieve an erection without stimulation.
