‘Platonic Love’ is a close relationship between two persons where sexual desire does not exist or has been suppressed or sublimated. The unification of the souls is important, not the bodies. The souls are attracted to each other rather than the bodies.
However, ‘Platonisexual Love’ is an affectionate relationship where the souls of the lovers are united and sexuality is also present. For example, the love between the husband and wife, and the lover and beloved. If the souls of the spouses are one, then it is ‘Platonic’; if they have a physical relationship, then it is ‘sexual’- Platonisexual.
