While I don't seem to suffer much from my circumcision, I am aware that sex would be even more pleasurable. I've resented my parents for a long time because of this. My blood boils everytime I hear someone trying to justify mutilating an infant and making a life altering decision for them.
The reasons are definitely bogus. Cleanliness is a non issue in the modern world, reducing chances of contracting an STD are most likely miniscule, and are what condoms are for. I've also heard people say a boy should look like his father, which is deplorable at best. I also despise religious reasoning, as it still violates the individual.
In my case, my skin is still fairly loose and can be slightly pulled over the base of the head when fully erect, but this isn't very pleasurable. I've also noticed that I have low sensitivity in the head, and that the skin there is thicker than it naturally should be; it appears dry, as well. There's also the scar, which is neither sensitive, nor aesthetically pleasing. Masturbation is really the only thing that makes me very sore, but that only happens if I go more than twice within a few hours, otherwise by 24 hours I can go again without too much loss of sensitivity or soreness.
I have no plans of restoring it unless science ever develops a way to grow a new one, complete with new nerve endings. I've tried to learn to just be content with it, as I can choose to dwell on it or be happy. I don't really miss what I never had, but am merely curious to what it would be like.
I'm sorry yours has had such a negative impact on your life. At least statistics have shown us Americans are catching up with the rest of the world. I believe it's only half of American infants now that are being circumcised, which is a huge decease since the early 90s. Ignorance truly can be an evil thing.
