I actually think I did gain some
Girth in my 20s. Most of my complaints were in my younger days. I have a very effective vasoocclusive mechanism which weirdly can give me tiny hard ons. I think the first time I tried
Cialis I had at 4
Inch diameter hard on. Totally bizzare. Was with a girl one time who experienced one of those and did admit that was not really normal, but later on I got better erections with her when I relaxed, closer to 4.8 which some might round to 5 and she was totally fine with that.
A major difference came from being diagnosed with pelvic floor dysfunction and slowly unlocking it and leaning how to relax it rather than contract it for sex. Basically try to shit out of your perineum. The more relaxed and romantically (not physically) attracted I was, the bigger my
Dick got. How perceptible it was to them I don't know.
I tried exercises back then and may have even triggered some damage and got no gains at all. They don't work for most people. I would say give yourself some time, investigate pelvic floor, find a relationship with good emotional attraction first where you can REALLY relax and go from there.
