I'm circumcised (due to phimosis that had made me virtually impotent) and in my opinion it's the best thing that ever happened to me. As for sensitivity, after circumcision there is a drop in sensitivity - this is true, and is necessary because there is such extreme sensitivity after circumcision with the naked glans rubbing on underclothing that walking is a torture for up to a month. But the drop in sensitivity is a temporary phenomenon. During sex the glans is engorged and hypersensitive and of course vaginal secretions and lubricants make sure the glans isn't dry. So the theory that a dry glans is desensitised is false.
Also, according to WHO, circumcision allows a drop in HIV infection rates up to 60%. This is the result of a scientific study. I don't see the above article making anything but unsubstantiated claims.

I'm circumcised and if you think circumcision does not decrease sensitivity you dont know what you're talking about. If you had phimosis it makes sense why circumcision would be "the best thing that ever happened" to you as you put it because before that you couldnt have full contact with your glans now you can but for someone who had a healthy foreskin and now doesnt have one i can easily say that circumcision is the worst thing that has ever happened to me. I can have sex for hours and hours without ejaculation, which makes sex very boring. The only reason i ever have sex is for my girlfriend's pleasure not my own because i barely feel anything but an emotional satisfaction. Not only does circumcision completely remove some of the most sensitive tissue on the penis, it also destroys the way the penis was made to function. And on top of losing all of that sensitive tissue, the remaining tissue is extremely desensitised which lowers sensitivity and pleasure even more. Also, having the glans constantly in contact with rough dry surfaces will make it desensitised no matter what. Think of it like wearing a watch, after a while you stop feeling the watch on your wrist. After your glans rubs against your pants for a long time, your body starts tuning it out. I can feel that there is missing skin, its like rubbing down your arm and you feel it end and your elbow and start again at your wrist. Its one of the weirdest feelings knowing and feeling that some part of your body was amputated. An intact penis has sensitive tissue half way down the shaft but a circumcised penis only has the glans and whatever remaining inner foreskin is left that only goes down around a fifth of the penile shaft which is also an unnatural feeling. Besides the physical effects it also has many psycological effects people never consider. I feel betrayed and depressed that i cant enjoy sex as i was born to enjoy it. And for what? Just because someone thought it'd be better for me to be circumcised with absolutely no justification. Who is to judge and say that I need to be circumcised? Its my body, I should choose. Why dont parents just leave their children uncircumcised and when they're older if they really want it done they can go ahead. Not giving someone the choice and forcibly removing a part of a person's genitals, male or female, is completely immoral and unjust. Circumcision is perminant and irreversible, and no one should have to endure a choice forced on them by someone else for their entire life. All things about circumcision being hygenic and "more sensitive" are absurd. Hygene isnt an issue because people shower every day, and if you dont then you really should. and how can it possibly be more sensitive when you remove half of the sensitive tissue and the rest calluses? Ultimately it comes down to taking the best pleasure away from a person by force. No one has the right to take that away from another person. Even when its a medical problem alternatives should always be explored because circumcision is an irreversible procedure. All I have to say is that if you are a parent contemplating circumcising your child, I hope that you read this and change your mind because if there was anything i could change about my life it would be to not have been circumcised and if my words can save another person from this then i'd be very pleased. It has taken so much from my life and my relationships, and years of depression that i would not wish this on my worst ememy. I think that those who are circumcised and cannot relate are just unaware of what they're missing. Ask any uncircumcised man if he'd want to be circumcised. I'm sure they'd tell you you'd have to be crazy. Knowing how good an intact penis feels no one would want to cut part of it off.

Are you sure you're not just overreacting? Is circumcision really that bad?

Circumcision is not so bad. If the religion/culture demands it then it must be done unless it puts the male at risk. As for demasculinizing or reducing sexual receptiveness or feeling, this is usually not the case. Circumcisions have been performed for hundreds of years, and no one I know whose had one has ever complained about it. I am circumcised and, while uncicumsized men may have more sensation in their penis', I certainly have ample sensation in mine.
