The penis problem

So, I'm the single mom of an almost 5 year old. I've mostly handled potty training already, but I'm having a little trouble still.So, question: do you need to hold your penis to pee? My son is uncircumcised, if that's relevant. We don't have too much of an issue with aim (thank goodness), but should he be pulling his foreskin back? I mean, he's still pretty small; there's not much skin in the fore, if you will. But there is enough to make his stream a little more spray-y. It just seems like I'd be asking him to pee all over his hands if he held himself.Is 1there some dude secret? I promise I'll only tell my son and then forget it if someone can clue me in.He doesn't have any trouble with the bathroom; it's not an emergency situation or anything. I'm just worried that in 10-20+ years from now he'll figure out that he's been peeing wrong and it's my fault.And, for the record, in case it needs to be said, I slide it back during his baths to make sure he's all the way clean. This is just a question about piss logistics via /r/Parenting https://ift.tt/2ILXXiB
