I get ingrown hairs and red bumps whenever I shave, no matter what I do!

I'm hate having body hair anywhere on my body. And since I'm a guy it always come in so thick and its annoying me. I mainly get bumps and such on my legs and butt primarily which causes me massive dysphoria. I've TRIED everything recommended to avoid bumpy skin after shaving but nothing works!!

I exfoliate everytime I shave and shower, I use SA cleanser 2 times a day, I moisturize my skin after shaving with lotion, I use a new razor everytime I shave, I wear loose pants, I clean my bedsheets weekly, I wipe every surface I sit on daily with antibacterial sprays. And I STILL GET BUMPS, ACNE AND INGROWN HAIRS!!

its getting to the point where I genuinely just want to chop my lower half off, I just want smooth and clear skin! Does anybody have any advice to help? Because Im going mad😭
