What is the difference?

Erectile dysfunction vs Premature ejaculation

Erectile dysfunction and premature ejaculation are the two most common sexual concerns among people with a penis, and they can occur together. One is about getting or keeping an erection; the other is about ejaculating sooner than wanted.

General information, not medical advice. For advice about your own situation, talk to a clinician, pharmacist or sexual health clinic.

In short

ED is about the erection; premature ejaculation is about timing. Worry about one can feed the other, so it often helps to look at both together.

What they have in common

Occasional episodes of either are normal; both are often linked to stress, anxiety or relationship issues as well as physical causes; and both are common and treatable through a GP, sexual health clinic or sex therapist.
