I was circumcised late in life (40 Years Old). I was a personal decision.
I can speak from experience. As a non-circumcised man, I found sex great. I would go hard and fast simply because I enjoyed it, because I felt more.
Then I got circumcised and sex became amazing. I felt everything, far more than before. I don't need to go fast to feel good anymore, I can take my time and enjoy the entire experience.
The best part of being uncircumcised was ejaculating. Now thats just the ending, the who experience is a massive and positive change.
My Doctors said that some men, lose sensation. I can only speak for myself and tell you it enhances it.
