Erectile disorder is a type of sexual dysfunction disorder that is characterised by difficulty in obtaining or maintaining an erection during sex and a decrease in firmness of erection.

While it is natural to experience difficulties in sexual performance during stressful periods in one’s life, those with erectile disorder experience the above symptoms on most or all instances of sexual activity over a period of at least six months, and can be something that has been present since the individual became sexually active (lifelong) or after a period of typical sexual function (acquired).
