Maybe you should look at your diet????If you have changed anything,that could be the culprit.Patty

My diet is quite high in protein. Would that effect it?

I could be your body for whatever reason is producing too much lubricant under your foreskin. It could be the way you masturbate, some slight irritation or even a fungus.
You have to figure out what's different.

A circumcision will eliminate the problem if it gets really dire.
Most women prefer a circumcised guy. He smells better and it is easier for him to put on a condom.
It seems to reduce your chances of catching aids from normal heterosexual sex.

Unfortunately, the op is more painful for adults and takes a couple weeks to completely heal. Also, you might loss a little sensitivity over time to the head of the penis. Most men don't find that it makes much difference to them.

Good luck

You could justs simply have an infection
