My son has had the problem, primarly at bed time. He is uncircumsized, with questions from dr. in the states about whether or not to get him circumcised now. His foreskin is extremely hard to retract, i have to do it to clean it properly. My Canadian doctor sees no problem, but i have had 2 doctors who see it as a possible/ definate problem. However, recently at bed time, he goes pee before bed and then i read him a story, rub his back or belly, depends on which he prefers that night. Some nights when i try and rub his back or belly he will be fussing with his penis. i ask him whats wrong, and he delays answering. His penis gets big like an erection and then when he answers he says he needs to potty again, however, sometimes he pees, sometimes he doesn't, and even if he does the erection doesn't go away. He had to pee 3 times in less than 30 minutes tonight. I don't know if this is because his foreskin doesn't retract properly, if it's an erection and what's causing it at bed time primarly, or a UTI. Occasionally he will have the problem during the day. If out in public i have to remind him to leave it alone, but it bothers him.
