My son had a tight foreskin, over the course of his life he has tried all sorts of ways to rectify it, but it ended up needing surgery at 15.
The Dr was adamant that he didn't want to circumcise him, even though it would have completely solved the problem, he said it takes away sensitivity and he'll thank him for it later. He operated and gave him a dorsal slit operation.
Now at 21, we spoke about it the other day, DS is sexually active and he said he was sooooo glad he wasn't circumcised.
