Will 100% hard erection come back? 50yo

I have finally made the decision to try this rebooting thing.  I didn't think I had an internet porn addiction but I believe watching porn, combined with too much masturbation, combined with strip clubs just ruined me.  I can get erect and can have sex but delayed ejaculation is terrible and lack of sensation.  My whole life up until late30's I would wake up with rock hard erections.  I want those type back but I read a lot of articles that say not to expect that at almost 50.  I'm hoping someone will tell me that isn't true.  I want to be rock hard, super sensitive, and really enjoy sex like I did before starting to do all that crap!

Hello sir. I am only 14 and im here. It is truly sad. Look at a few of my posts. Im in a horrible situation with a numb penis supposedly from fapping too much. I think the reboot will help you recover. 90 days. I dont knoe if there is hope for me anymore though

Not sure Simba. But I think it's definitely worth a shot. You can still have sex, that's great news. Quitting porn can ONLY help. All that may have changed as you've aged is testosterone dropped a little and your general health may not be as good (I'm guessing here, you might be fit as a fiddle). I would quit the porn for good, and masturbation. Get in real good shape and promote that testosterone production.
Edit: not a doc
