Probably need some better razors. Many of them are junk. Sometimes I go over one spot quickly like 20 times instead of trying to power through. A sort of erasing motion isn't as bad honestly. My tips are don't let your hair grow too much, get some clippers or something for your body and use the first. You can also try waxing which will make the hair stay gone for a week + maybe longer. The T blockers help a ton. I don't have to shave my body very often anymore. Every couple of weeks and my face only every 2-4 days depending on how clean I want to look.
