I used to get it all waxed when I was younger, but my current wife likes the hair, so I leave it and just trim it so it doesn't get out of hand.
But the potential bonus of getting it waxed is that your esthetician might give you a happy ending, if you're into that sort of thing. For me, when I got waxed my first time, I had a major boner, and I was doing everything I could to hide it, and I even apologized for it too because I was so embarrassed. Later in the session, things were about to get messy if you know what I mean, and I tried to turn to the side because I didn't want her to see because I though I'd get in trouble, and she straight pushed my hand away and just went to town. Lol, and to make it worse it even got on her shirt. I was beyond embarrassed. But she was super cool about it and said it's not that rare. And I had kept going back to her for the waxing, and at the end, she would just you know do her thing, if you know what I mean. So there's that possibility. I certainly wouldn't go into expecting it though because then you just look like an asshat. Perhaps I just had a really open minded esthetician. But I think if you go into it being embarrassed about it, they are more likely to throw you a bone.
But yeah waxing is great because while it does hurt the first couple of times, I think it feels the best afterwards. Not to mention that with shaving you have to keep up on that shit constantly otherwise 3 or 4 days later you end up with the pelvic blades of fury that the ladies hate.
