Can nuns be married

No they cant be gay. They dedicate their lives to god.

Roman Catholic AnswerThe term "Gay" usually refers, in modern parlance, to a lifestyle which involves an active homosexual orientation. This would be completely incompatible with someone wanting to lead a chaste life dedicated to serving God. The question, as asked, doesn't make sense, it would be like asking if a woman could be a man.

General Answer

Yes, Nuns can have same-sex attraction. However, they aren't allowed to express it, partially because of the general catholic stance on homosexuality, but mostly because they're nuns, who can't have sexual or romantic relationships (symbolically married to God).
