I began to think about circumcision after an experiment an earlier partner and I tried for fun.
As a result, where possible I would wash twice a day.
I noticed while living in Europe (where circumcision is in the minority), that many men would have a strong odour, like the one I was familiar with, in winter.
When thinking that in countries such as Italy and regions of France, showers are a once or biweekly affair in winter, I could understand why this odour could become so strong.
Hygiene is no longer an issue, the lack of foreskin keeps the penis clean at all times. On the contrary, I find intercourse improved 10 fold since the circumcision.
The few microns the skin that the glans may have thickened makes no difference at all to sexual receptiveness and I find it in some ways it is more sensitive.
