Submission to a woman’s authority is natural for some men, but not for others. Some men must be “broken in” so to speak, and trained. That would be my husband.
As I’ve read and learned from first hand experience, that training must be carefully paced, consistent, and employ an effective punishment/reward system that takes into account a person’s individual characteristics.
If both of you are new to this, and especially if he is, I think it’s a mistake to move too fast, to try to introduce to many things at a time. Take it slow. Before you move on to the next thing, give him time to both physically and mentally adjust to his new circumstance. Don’t overwhelm him with change. He has to get used to it, and certain things may take him some time. He has to get to the point where it just becomes a normal part of his experience.
This applies to every aspect of FemDom, whatever your particular interests may be: obedience training, household chores, pussy worship, enforced chastity, orgasm restriction and control, body massage, tease and denial, spanking and corporal discipline, ruined orgasms, foot worship, prostate milking, ass worship, cuckolding, date preparation, oral clean up duties, strap-on training, humiliation, feminization, forced cocksucking, anal submission to your Bull, or what have you.
Ultimately, I think my husband submits to my authority because he loves me and is hard-wired to please.
