What is the best age?

I posted a variation of this on another site, but would appreciate your responses to this little poll:

Q: What is the best age for a male to receive chastity cage / tease and denial training by a Dominant Woman? (Please pick only one)

A. Teen years - Young males are easier to train than older males. Chastity cage training at this age will eliminate the chance of unwanted teen pregnancy, and will promote the males submission to females throughout their lives.

B. 20-30 Chastity cage training at this age will maximize the males sexual frustration and tension. This will be pleasing to their dominant woman. 

C. 30-40 Chastity cage training at this age will virtually eliminate the "lazy husband" syndrome, and make the male more attentive to their woman's sexual needs, since failure to obey will normally result in additional chastity time, and / or ruined orgasm's.

D 40+ Chastity cage training at this age will promote harder and stronger erections as a man ages, and testosterone levels begin to fall.
