I am uncircumcised. in the past, women I have been with, who had previous partners that were circumcised, did report some minor differences.
ie, they had to adjust their technique, to account for a difference in sensitivity.
I discussed it with a couple of long term partners. From their reports, the differences were very minor.
I defer to their much wider experience with... penises.
That being said, my understanding is that FEMALE genital mutilation, is a far more... harmful practice.
Not everything is equal, and in this case, I think brining up the MALE equivalent, is not reasonable.
