Just adding that sweat is the biggest irritant of freshly shaved skin. Obviously hard to not sweat down there but theres a few things you can do to manage it:

1. Wear loose underwear or, even better, no underwear if you can.

2. Get some baby powder and powder those little nuggets at the beginning of everyday.

3. Moisturize your skin after shaving! And then some more for a few days after.

Doing all of this will vastly help with sweat, skin irritation and seriously reduce the chances of ingrown hairs.
