Pointing at Penis

2 year old toddler boy. Not talking yet and not potty trained yet - about to start once I can get time to not leave the house for a few days. He started telling me in the last week when he goes in his diaper and points at himself to let me know. Today he ha been doing the pointing but his diaper is dry. It’s bath day so I put him in the bath early but all during the bath he kept pointing at his penis. I looked up symptoms for a UTI and he doesn’t have any of those. Is this just normal? Or could it be hurting him? Hard to tell when he doesn’t say words 😭
