I have tried a proper wax treatment once, and yes there is a bit of pain, but it doesn't last, plus you get an adrenalin rush later ! WOW !!
But the best thing is the feeling of bareness, it's like you have been given a new penis and testicles! Also, a neat triangle of remaining hair on the pubic triangle looks gteat, and can 'add length' (trick of the eye) to your penis. I am going for a second ever waxing next week, last one was in November.
The hairs grow back quite softly, there is no itch,
