Before & after thoughts - 2.5 months later
I was cut in April, stapler method at Circumcision Pro in the UK, aesthetic / non-medical reasons. I've had the all-clear for several weeks now, sharing my thoughts for others:
Appearance: really happy, I love seeing the exposed head every time. The scar is still slightly hard / raised on the underside but overall it's progressing well - I've read it'll continue to flatten out and I'm using bio oil & scar sheets when I can.
Sensitivity: not noticed much difference, maybe slightly less sensitivity during the day but I still sometimes 'feel' my penis when walking around. I'm cut slightly loose so when very soft and sitting down I have some skin covering the rim of the glans which might be a factor. Orgasms feel the same, see below.
Sex: amazing, feels better because I don't have foreskin covering the head at any point during sex and every thrust feels more intense as a result.
Masturbation: the biggest difference, though I usually masturbated like a cut guy even when uncut, so if anything it's easier without any skin to hold back. Overall it maybe takes a bit longer on average because it's a bit more restricted to use my (remaining) skin if I wanted to.
Like others say, no need if you don't have a medical reason, but if you have a personal desire anyway then it's been worth it so far.
