Can the tissue in your penis become harder

Can the tissue in your penis become harder/tougher due to PE or over doing it? Because some times when I feel my flaccid it feels abit tough not all the time. Why is this? Also could having tough tissue make gains harder to come by?

I’ve experienced a toughening of the penis before, the only two times I have experienced it was when I almost completely stopped my routine(which is clamping and jelqing) or did stop p.e. When my penis felt hard/tough my erections were not as big and things like jelqing seemed completely useless.

I stopped peing for a period due to an injury almost exactly a year into my p.e adventure. Although it was an un welcomed break, it served as a nice deconditioning break. About 3 weeks into the break I noticed my penis just felt harder and more dense/condensed. I came to the conclusion that this was my cemented size as my erection was smaller then my largest point but bigger then when I started.

When I came back from my deconditioning break jelqing felt useless but only 3-5 days of using a heating pad and clamping returned my penis to its softer more pliable self.

Wann8, the stifness can be a result of the penis taking in more blood through PE.

Also, do you do warmups? I noticed that when I would jelq without a warmup my flaccid would be a bit hard.

Thanks for the replies,
Going to try longer warm ups and do some extra warm up wraps and massaging throughout performing my routine and do some more stretches which might make the tissue more pliable and supple again.

If it is because of the penis allowing more blood in, would the effect of having toughening of the flaccid penis subside over time since it can’t be a bad thing the penis accepting more blood flowing in?

Thanks!
