Chastity and orgasm denial discussion

I’m looking to purchase the Neosteel sports model chastity belt, but I have two questions about the measuring kit. Thanks for any assistance.

1. Center hip front over the scrotum sac (between testicles and beside penis) across to rear center hip (from bottom edge of front leather belt to bottom edge of rear leather belt).
2. Center hip front (bottom edge of leather belt) down to top of penile base.
