Got circumcised in December 2020 @ 34 years old. On a great day, before my cut, I can just about reach 6.00 inches erect with ruler pressed against pubic bone. (And no, I did not count the foreskin.) It has been 1.5 YEARS since getting cut and my fullest, strongest erection barely makes it to 5.75"...barely...and that is if I press the ruler down a lot, possibly cheating. Most days, when not totally rock hard, it is about 5" to 5.5". In conclusion, I am 100% convinced I lost about at least 0.25" after my circumcision.
Now, granted, I have not measured myself fully erect since my early 20s. It could be that I naturally lost a little size as I am getting older. This is not unheard of.
Concerning sex, it is comfortable as before. It does not feel any better or worse.
My incision was done by hand and the surgeon wasn't that great. Top of penis incision looks fine, bottom part of penis looks a little jagged. Wish he used a device so I could have a "smoother" looking incision. Oh well. A lot of stuff I know now I didn't know back then. At least my junk works fine.
How have others' experience been?
