Can we train our penis / dick to get that hard and desired erection??

Hi, good afternoon to all.

The discussion today is about if people with PIED, or ED, or simply people that cant get a good erection can train this in some way to finally, with rebooting and train we can get that erection.
What happens to me is that im on a week and a half since my reboot. Im touching my dick a lot, even shaking it but without eyaculation and without porn, without external vido/photo estimulation.
My question is: Is this bad to us?? To touch or penis a lot without eyaculate??

And the other matter is: Can we train our penis in some way to finally get that desired erection??

Thank you all. Open discusion 

One of the process of rebooting means to fix all the problems associated with PIED. I also had the same issue of not getting hard when I stopped quitting, because I had trained different muscles/nerves to get erect only for jacking of to porn by sitting in front of pc.

There are several exercises specifically geared to increase your muscles/nerves for erection, plenty of them are online, the most popular one is to do 'kegel' exercise, then squatting, functional abdomen exercises should do you good. Remember to keep yourself healthy, and fit.
