Razor burn?!?

Elle

Okay so I’m 15 and i feel like everytime I shave down there i ALWAYS get razor burn i cant remember a single time my down there was perfectly clean with no red spots. I’ve tried just trimming and not shaving all together but somehow i still get red spots. I’m not sexually active or anything like that but i really just wanna wear a bikini and not constantly be worrying about what everyone is seeing, I’d be a lot more comfortable if y’all had any advice on how to get rid of this or if y’all have the same issue?
