Marinera is pretty accurate, at least as far as an “average” goes, if there even is one. There are just too many variables involved. I did PE for about 2 years several years ago. I gained over an inch in length, and nearly 2/3 inch in girth. Variables? Smoking, drinking, etc. Hindered my gains? Probably.
I got out of PE for about 4 years, zero maintenance. I lost about 1/2 my original girth gains, but only 1/10 of an inch of length. Also went from a 10 to a 7 in EQ over that time.
I have been back at full-time PE for over 9 months now. I have gained back all of my losses, and am in the process of cementing gains which will put me over my previous largest size from 4+ years ago. I’ll soon be updating my stats in the PE database. My EQ is back up to about 8, but that’s just from fatigue. I’m closer to 9.5 after rest day(s) now, and the morning wood is back also, which was about non existent when I re-started PE. I have not jacked off in a year, which I used to do semi-regularly when I did PE the first time around. I get laid enough with the wife, I don’t have the desire to jack off (get laid 4+ times per week). I am a believer that masturbation is counter productive to PE, and that is something which is hotly debated here, some believe it, some don’t. I don’t think regular sex hinders gains however, but at least for me, masturbation is something completely different. It’s funny, about once a month I’ll even have a wet dream! I attribute this to the benefits of PE, I hadn’t had those since my late teens! These can happen even on a night when I got laid before going to sleep. As we age, I think PE has even more benefits to EQ and overall sexual health.
It’s been hard work getting the lost gains back, I didn’t get the “newbie” gains all over again like I had hoped I would. This time around, I’ve had to add clamping, pumping, ADS, etc. The routine has been amped up to nearly an hour a day, 5 days a week. Everyone is a little different, there’s just too many variables…
Another thing I will say, any/all gains attained should be MAINTAINED for life, if you want to keep them. I learned that the hard way, and there are other vets here who have lost almost all their gains due to inactivity. I truly believe this is a lifetime thing, not to be taken lightly. If you truly want a bigger dick, you will need bullet-proof dedication, and have to stick with it no matter what. That’s the bottom line, DEDICATION.
