Pumping as a way to help erect traction gains

I’ve been at PE on and off for a while, have had some success in the past, but have always had a satisfactory size imo already, so didn’t stick with it.

Now I’m looking to make some considerable gains. Starting stats are 7.5x5.5 and I’d like to get between 8x6 and 9x6.5

So this is my routine, really just starting here but I do not like jelqing. It borders on masturbation, something I’m actively avoiding, and its given me a bit of a baseball bat in times past. Surely my fault to some extent, but I won’t be doing it.

I currently stretch for 4-6 hours a day in my x4. May take it up to 8. I pump every 2-3rd day to between 3-4 Hg for maybe 10 minutes. I may take this up to two 10 minute sessions every other day. My hope is that the pumping will help convert the flacid gains from stretching over to erect gains.

After a few months of this I’m gonna give clamping my attention as I’ve read thats great for girth, but may keep me from getting any longer.

Certainly open to any input you guys might have for me. Thanks for reading.
