Intimate shaving

Hi guys, I'm here looking for tips on how to: - shave your fucking balls..I never manage to get them completely hair free - how to avoid the rash afterwards - other ways to remove hair from your dick to you assI really like the feeling of being completely shaven because it's way more sensitive but I'm not particularly fond of having ingrown hairs and little ulcers all over my downtown area. And my wife isn't such a big fan of that neither but I doubt her trick of daily shaving is the solution. Yes, I'm straight, but I don't discriminate so why would you and my guess is you guys have more combined experience with this than the whole straight male community globally does
