Big als the man you want to reach out to here. He doesn't mind a Pm.
I'd probably look at dropping jelqs and working on edging. Personally I hate edging but that's because I get ball ache easily. However I still edge and put up with it as it helps EQ.
So yeah, edge and kegal. Kegal while edging, erect kegal and kegal when just sitting around.
Reverse kegal. There's a good shout for evening out kegals with reverse kegals. So 50/50.
I do a maximum of 100 each. I find it's really given me a way to force blood into my shaft. I start erect, I reverse kegal for a few seconds them squeeze a regular kegal. This feels like a pumping action and fills my dick up. This is a fun thing to do during blow jobs. Mrs inches face when I suddenly fill her mouth with meat is priceless.
Maybe if you're an avid porn fan, reduce your porn intake. It's a diminishing returns thing. At first it's great, then you desensitise to it, then you need more, then it stops working properly, then for some has long term detrimental effects on their sex lives and EQ.
So in a nut shell you need to build your dick up more. I've just finished watching a series of YouTube videos by a guy called janus bifrons. His first video on the angion method is really interesting and is something I'm considering for the future to further my gains, cement my gains and ensure a good EQ. Definitely take a look, it was specifically designed for erectile issues.
Lastly, I repeat, reach out to big Al. He'll give you a tonne of extra advice and a whole wealth of experience that is in far excess of what I can give you.
With anything you decide on in the end, consistancy and patience is the key.
Good luck!
