Hey, I think it is awesome you are making some lifestyle changes. That's not easy to do. And that you are making sunshine out of this lockdown and making positive life changes. That's great.
You are masturbating a lot. That might take a toll after awhile and yes, think that could be due to too much masturbation. In general, masturbation is a fine activity with no repercussions. You are making some great life style changes but it also may be throwing off your hormones. In younger men, one of the biggest reasons for ED is low testosterone.
But you really aren't describing impotence. More that you don't feel your erection is as firm as usual? Are you getting bored masturbating? Could this be mental?
I like to add that I have got 3 erections and a morning wood yesterday but today I can't seem to get erect
Should I stop trying to mastrubate
