IM TIRED OF THIS RED BUMPS ON MY 🐱

Okay it’s my 18th birthday tomorrow and I need to get this puss shaved nice and done. I’m tired of red bumps im tired of her not looking good, I’ve had it of buying a nice new clean razor and waiting a week to shave just so it can be so nice, well nothings doing the trick. Girls please help me. What can I do? How do I shave 🙄 what can I use ? I was never really taught how to shave right... help a girl out
