I have a question over husbands. What can you wear or do with your husband in private? What is allowed in Islam?
The rule regarding both clothing and sexual enjoyment is that everything is allowed unless it is specifically forbidden.
She can wear anything and nothing. Spouses are permitted to see each other naked.
Women are strongly discouraged from wearing male clothing, that’s the only important limitation I can think of regarding what she can wear in front of her husband.
As for what they can do, they can do all that’s customarily done between a husband and wife throughout the world, except for three things: Anal sex, sex when the woman is menstruating, and anything that causes harm to either person.
