Shaving your 🐱

Hello guys! I need help :( so I’ve been shaving down there for about a year (I’m 15, I only do it for myself I’m not sexually active or anything) and a couple of my friends say they have no problem with it but when I try it hurts and leaves rash/bumps. I still do it but I need a way that won’t hurt or anything. Just FYI I have sensitive hair, that still irritates me a bit tho and doesn’t even take the hair all the way off. I use coconut oil, I don’t wanna put other stuff down there. I usually shave down or sideways too so it doesn’t hurt but still I don’t like how I can’t get bald and that still hurts sometimes. I don’t wanna get waxed because I don’t have money. Tips?
