Can two people with a homosexual orientation live together if they've had sex in the past?

The clear Biblical teaching of TfT says that any sex with another person, outside the ‘one flesh’ male and female marriage relationship, is sin.

In terms of the possibility of two people, previously in a sexual relationship, continuing to live together without sex, this may be possible for some but not for others. It would be a similar situation for two heterosexual people. It is very easy to assume that sex is the only possible sin in a relationship. It should be recognised that envy, greed, idolatry and many other sins can be there in any relationship. In some they can be worked through in a way that means growth and wholeness as they know more of themselves and even more of God’s love. There will always be situations, where the battle with overcoming sin is so great that breaking off the relationship has to happen.
