Haha...The most well known is erectile dysfunction...well we know what this is about...the inability for men to get it up! Being frigid is also a sexual disorder and so are having an overactive and inactive libido!
These can affect men and women...well except for the erectile dysfunction! haha
Yes it is lizzieM. Being a nymphomaniac is a mental condition that needs medical attentionn. Other forms of sexual disorder is the inability to orgasm despite stimulation...as stated they are usually mental and psychological issues but they are real.
