Here’s a study on it. Basically the foreskin nerves are “touch” nerves, and all touch nerves get reduced sensation with arousal. The number of those touch nerves drops significantly with age as well, with a 90% reduction by the time your 45+. It’s other nerves (mainly in the corona and near the frenulum) that are focused on vibration and temperature, which mainly contribute to pleasure.
Ultimately the “ejaculatory latency time” doesn’t show a difference, even across various reasons for a difference in the quantity of touch nerves.











Didn’t know that, was literally just the first source I found.
Wikipedia’s article has a section on it, with about 4 difference sources that all seem to conclude the same though. Maybe they’re all bug circumcision propaganda, I haven’t really looked into that part of it.
