Inner foreskin gets sore - how do I desensitize it?

[jdm]

I know this topic is old, but I came across a study that actually found a measurably effective method of achieving inner foreskin keratinization in a matter of days. I don't really care too much about this topic, but I couldn't keep this to myself as there are surely guys who would be interested in this, so here you go:

Taking a clue from these studies, Drs Andre Pask and Roger Short of the University of Melbourne and colleagues applied estriol cream to the inner foreskin of 2 men. The epithelium underwent keratinization within 24 hours and the positive response-up to a 4-fold increase in keratin production-persisted for at least 5 days.

Yeah, that's an interesting topic. I looked into it a few years ago, and wrote a thread about it here.

I wonder if there's been any new research since then. I'd be interested to read your insights.
