Yes, there is a vast increase of sensitivity with foreskin restoration.
The restoration process dekeratinizes the glans and the inner foreskin, which improves sensitivity.
The inner foreskin adds a whole new dimension to sexual feeling that a male without a foreskin cannot experience. In my case, the new inner foreskin is almost more sensitive than the glans.
But each case is different. There are no standards to circumcision, which is why the damage to sexual feeling/function varies so much. The wounds to the penis from the mutilation vary wildly in location and depth; the scars can be located anywhere from just below the glans to 1/2 or even 2/3 of the way down the penile shaft.
The usual loss of sexual sensitivity from circumcision is roughly 50-75%, and can even be more in some cases. I experienced a similar loss to your partners.
Restoration is a very slow process, taking several years. I did experience a marked increase in sensitivity just three months into my restoration. I had an increase in the intensity of orgasm, as well, and quite an increase in my libido.
Surgical restoration doesn't yield satisfactory results. They transplant skin, usually from the scrotum, grafting it onto the penile shaft. Since nerves do not regenerate and "reconnect" there is no feeling in the new foreskin, it is just numb. The skin also has the wrong texture and an odd appearance.
Non-surgical restoration methods are successful, but they take several years to acomplish.
They all involve putting tension on the penile shaft skin, which allows new skin cells to fill in, slowly and gradually extending it into a new foreskin, with most of the same sensitivity of the original
There are three techniques; taping, manual restoration, and devices.
I use the most popular of the devices; the TLC Tugger. I'm also a member of NORM, the National Organization of Restoring Men.
More than 200,000 guys are restoring their foreskins, to regain some of the sensitivity/function destroyed by the damage that is circumcision. Foreskin restoration will not repair the permanent neural/vascular damage of circumcision, but it does vastly improve sensitivity/function.
You can google "foreskin restoration" for more information. There are sites for guidance, advice on techniques and emotional support, and lots of different devices.
Foreskin restoration is the best thing I've ever done for myself. It feels so much better, and I also feel more whole and complete as a man.
Circumcision is a fraud and a hoax.
A foreskin is not a birth defect; it is a birthright.
