Romance is not appropriate between people of the same sex, just as it is not appropriate between siblings. Think of the intimacy of healthy sisters. They are close emotionally, often having intimate access to each other’s lives. This relationship can be a special blessing, a cherished reality. But it would veer into unhealthiness if one sister was unreasonably jealous of the other having close friendships with anyone else, or if the sisters felt possessive of each other’s time or emotions.
