The husband may have a fear of hurting his wife accidentally. He might be aware of his own strength and lack of finesse in such physical actions. So he believes that leaving his wife on her own two feet is the safest option for her well - being.
A reason could be cultural. In some cultures, there are specific norms about physical contact between spouses. Picking up one's wife might be seen as too forward or inappropriate. So the husband, influenced by such cultural beliefs, thinks it shouldn't be done.
One possible story could be that the husband has a traditional view of gender roles and believes his wife should be in a more 'protected' position rather than being physically 'picked up' like a child. For example, he might think it's disrespectful to her dignity as an adult woman.
One reason could be anger management problems. If the wife has difficulty controlling her anger, small disputes can turn into physical altercations. Another reason might be substance abuse. If she is under the influence of drugs or alcohol, her inhibitions are lowered and she may become violent towards her husband.
It could be for the sake of relationship growth. By feminizing her husband in certain ways, like getting him interested in home - making or nurturing activities, it can create a more balanced partnership. They can share responsibilities more evenly and understand each other's roles better.
The husband could suspect the wife if she has become distant emotionally. She may not be as affectionate as she used to be, which can make him wonder what's wrong or if there's someone else.
One possible reason could be that the wife is a very dominant personality. She likes to be in control and the husband, being more passive or sissy, allows her to take charge. For example, she may be used to running things at work and brings that home.
For fun. It's a simple way to add some humor to their relationship. Maybe they are bored with the daily routine and this is a way to break the monotony.
One reason could be that the husband has a higher sex drive than the frequency of their sexual activities as a couple. So he resorts to masturbation to fulfill his needs. Another reason might be that he just needs some solo time for relaxation without any pressure, which is different from sexual activities with his wife.
One possible reason could be that the wife is unhappy in the marriage. Maybe she feels neglected or unappreciated. For instance, if the husband is always busy with work and doesn't spend enough time with her, she might seek attention elsewhere.
Boredom in the relationship can also play a part. If the wife feels that her marriage has become dull and unexciting, she may be more likely to be attracted to someone else and start an affair. This can lead to the husband being in the position of a cuckold. Also, sometimes a new person enters the wife's life who offers something she feels is lacking in her marriage, like more attention, adventure or passion.
Sometimes it's for artistic or creative purposes. For example, if the wife is an artist or a photographer, she might want to create a unique visual piece with her husband as the subject, dressing him as a woman to add an element of surprise or to explore different aesthetics.
