MHSDD is categorized into subtypes depending on the way that symptoms manifest. The subtypes include:
Lifelong/generalized. In this type, the man has never been interested in sexual activity, either with a partner or alone. Acquired/generalized. In this type, the man has had sexual desire for his partner in the past but no longer has an interest in sex with any partner or alone.
Acquired/situational. In this type, the man has previously had a sexual interest in his partner but no longer does. However, he is interested in sex with a different partner or alone.
