Functional Femininity

When someone chooses to change their gender to female not because of gender dysphoria, but for practical, functional reasons. In certain situations becoming female might be desirable for pragmatic reasons. To obtain citizenship by marring a heterosexual male for example. Or simply to become a stay at home wife due to a difficult job market. In prison sometimes it is necessary for a male to become female simply for survival. Someone practicing functional femininity may be open about the fact they are adopting a female gender purely for pragmatic reasons, or they maybe choose to conceal it. It's not unheard of a male to agree to function as a female for a heterosexual male in return for a VISA via marriage. Their husband being fully aware they are practicing functional femininity and that they do not truly consider themselves female. Often there is a formal agreement of specific terms. Such as permanent chastity, various (sometimes extreme)surgical enhancements and even castration and/or penectomy. This acts as assurance that the male will continue to function as a female permenantly in the long term. These terms are common when a husband is concious of the fact their wife is a male practicing functional femininity. This kind of arraignment is common with east asians attempting to move to western countries.
