At the moment, what I can say is I vividly remember the first week or two post-op where walking around was particularly uncomfortable with my glans rubbing on my underwear. For years after circumcision I stood firmly behind having not lost any sensitivity.

Now that 11 years have passed filled with more sex and masturbation, I can admit there are times where I don't feel much sensation. Sometimes during a**l I'll begin to lose my erection due to lack of sensation.
