shaving.

Alicia💋
Okay ladies so whats the proper way to shave? Ive tried sensitive skin products but i get alot of razor bumps and i feel like there is more hair coming in? Im 21 so that should be over and done with. Ive tried waxing (takes too much time and money)  and shaving different ways but i still get those ugly razor bumps??? 
Any tips?
