Some guys just have more sensitive skin. If you still want to try shaving, try getting a double-edged razor, one of the "old-timey" ones. A good soap brush, some high quality shaving soap. It really makes a world of difference compared to shitty gillete 43898 blades that just cut you up and irritate the skin. Another pretty easy option is waxing - a decent enough home waxing kit is like 50$ on amazon. Just apply and pull, smooth as can be for the better part of a month. Doesn't even hurt that much, you don't have so many nerves down there.
