My son is 6 and has not retracted yet, to my knowledge. When my husband (his dad) talked to him about it he got very aggitated, though and said he didn't want to pull the skin back because he was afraid that it *might* hurt. Then we started asking him if it did hurt now, and he insisted that it did not.
I haven't been getting into his business for a couple of years now because he's been asking for privacy, and I feel like we should respect that. But I have to admit I was a little worried. That's how I found this forum, actually! Looking for answers!
When I asked him if he could just please try to see if he could pull the skin back, he looked at me with puppy dog eyes and said, "Can I watch you do it to yours first, mom?". How. Cute. Is. That. ?
Hope I didn't get in on the poll too late!
