I have fairly similar beliefs as you, I believe sex before marriage as well as masturbation and lustful thinking distances a person from God. In the Church, Chastity and virginity are virtues for men and women, virtue includes your thoughts though, not just body. Not much virtue for being a Virgin if you are constantly fantasizing about sex and/or masturbating.
I wouldn’t want to wear a chastity device unless it is necessary to curb sinful tendencies. I think in some men it would be necessary as masturbation can be a strong compulsion, hard to break but not impossible.
I have decided not to wear a device, I have been struggling against the masturbation habit for years without a device and I find God grants me some progress, I have made it past a month probably a dozen times, currently I’m at 5 months since I’ve masturbated.
also, the device might arouse me more because it might draw my attention to my genitals more.
God bless you
