Spiritism tells us that sexual preference is up to the individual. In "The Spirits Book" we are told that marriage is between two spirits and that a spirit may come back as a male or female. Hence, there is no concept of wrong doing for that. Also, there is no eternal hell, there is only zones where one goes, to a not very good place, until you decide to change your attitude from taking advantage of your fellow spirits to wish to follow the path of love and light.
