Shaving dilemma 😬

Every. Single. Time. I shave i get really bad red bumps around the whole area and sometimes they even become infected and seep or have white heads. I use the best shaving foam i can find and sharp razors i dont know what im doing wrong. Hair removal cream leaves stubble and a bikini wax is out of the question as i am only 16 and my kother doesnt know im sexually active. Please help 😬
