I need shaving tips/products badly!!!

When I go to shave my downstairs I pretty much ALWAYS end up with razor bumps and ingrown hairs. It’s so embarrassing especially in the summer time. Shaving cream doesn’t make a difference. Does anyone know of any specific products or methods of shaving that have helped them fight this? The only thing I’ve done that has -kind of- helped is shave in a sideways motion, rather than completely against the grain. Pls helppppp I’m dying over here
