Could abstaining from masturbation cause ED after awhile?

For some reason I decided to stop masturbation and quit porn a while ago. Maybe a little less than a year. I masturbated a couple of times but the time between each was more than a month. Currently noticing my penis when flaccid is… like really flaccid. When I try to think of something it takes sometime and needs direct stimulation to start to get hard and doesn't stay long if I stop the stimulation with my hands. If I continue the stimulation, I feel that I'm about to cum right away. So I think less than 2-3 mins is what it takes for me. I'm not married and don't have a girlfriend and I thought that stopping masturbation is good for your sexual health and would make your libido higher. Now my libido is kinda low but not non-existent and I think ED is bad too. I'm late 20s.
