Shaving issue

Meg

I shave my legs ( because that’s what every famale eventually has to do if that what they desire) and every single time I do so my legs come out rough with razor burns and just not smooth like I want them. I’ve tried almost everything from oils shaving cream soap exfoliate and even this cream called “coochy” I’ve changed out razors used really nice (EXPENSIVE) ones to cheap ones male and female. Nair burns my skin but I’ve never tried waxing, although besides that is there anything I haven’t done that I should try? Please help!!!
