Welcome!
my advice is:
1/do a very intense warm (hot water or other) like 10 minutes, or even 15 you can repeat this at the end of routine or even in the between, of it. Warm will help a lot…don’t do like me, in the beginning i didn’t understand it.
2/ start with stretching. lateral, and up down. also in the middle position. You can use different hand position,
the one under the head pulling away the skin or also other variations (more near the base, or under the head, but using the skin) also you can try v-stretch and other kinds (read on it)
3/ you can repeat some hot water warming and do some jelq the time you have…20/30 min is OK, for me.
(there are many variations as you can read) and some squeezes. I use a little lubrificant, it’s a kind of wet-dry jelq. I have also restored my foreskin (like 80%) Do it slow, do it like you expand you son and with the time you get permanents results.
During the day you can use some PC flex. Hot water or similar is great to help this process. You can use and ads for a hour or more during the day, if you have the possibility (I use penis+ device)
The first months, don’t force too much, it’s not a competition! You need time to have results. Don’t hurt yourself.
It’s possible to hurt and to damage. But if you listen to your body, you can be safe. So, take it easy. Easy…but consistent!
For me, I have gained one inch (now some more) in more than one year. Now looking for a possible second inch.
Good luck!
