Nair on pubes

Hi guys, I have a question regarding nair. I (23 m) have been shaving my pubes since I was like 16 and everytime I shave I experience pain (mostly underneath my balls / inner thigh area. And I’ve noticed I have been chaffing a lot recently down there. So I’ve been thinking of using nair instead of shaving because of my sensitive skin. Has anybody experienced the same thing? And should I switch to nair if shaving hurts too much?
