"I saw my dad shaving his dick and balls and he had a total hard-on. It's the first time I ever seen him with a boner. When I asked why he shaved everything he said it's more comfortable. He showed me how to do it which was great (easier when its hard he said). But the razor burn every day sucks. Aren't there other ways?"
It is more comfortable - in several ways. Not as hot (hair is an insulator), less sweaty (hair is an insulator), so less scratching of the crotch. Hair can chafe during sexual activity --- both your cock and a woman's vagina.
Shaving with a hard-on is better. It stretches the skin tight so the razor glides easier and smoother. Razor burn? If you use too much pressure, you're scraping off a layer of skin. Same as shaving your face, let the weight of the razor do the work.
There are alternatives. Some guys pluck. Some guys get waxed. Or go for sugaring. And the aestheticians rather expect and prefer you to get an erection.
Some go for laser hair removal - which is permanent after about 7 sessions. It's not painful (or shouldn't be, anyway), but it can be pricey.
The bad news: Laser hair removal will not work on Blond, Grey, or White hair.
The good news: There are now lasers approved for in-home use. They can be pricey - the good ones, anyway. But doing it yourselves can save quite a bit of money. Even your mom could use it. Maybe that would be a good enough excuse to get Dad to pay for it.
