What is erectile dysfunction?

Erectile dysfunction (ED) is persistent difficulty getting or keeping an erection sufficient for sexual activity. Occasional difficulty can be normal; a repeating pattern may benefit from medical evaluation. ED can have physical, psychological, or mixed causes.

How does online ED treatment work?

Legitimate online ED care uses a licensed clinician who reviews your health history and symptoms remotely. If appropriate, they may prescribe FDA-approved medications through a licensed pharmacy. Treatment is never automatic — a clinician makes independent medical decisions.

What is the difference between Viagra and Cialis?

Viagra (sildenafil) and Cialis (tadalafil) are both PDE5 inhibitors used for ED. Sildenafil is often taken as needed with a shorter window; tadalafil can be used as needed or daily with a longer duration for some men. A clinician helps choose based on your health and goals.

Is low libido in women normal?

Sexual desire fluctuates with stress, hormones, medications, relationship factors, and life stages. A persistent drop that causes distress may be worth discussing with a clinician — especially when it affects your wellbeing or relationship.

Are Feel Ready guides medical advice?

No. Feel Ready guides are clinician-reviewed education to help you understand options. They are not a substitute for evaluation by a licensed clinician who can review your full health history.

How are guides organized?

Browse by topic — erectile dysfunction, sildenafil, tadalafil, women's health, and relationships — or by timing goals: support for planned moments, longer flexibility windows, or whole-person women's and couples wellbeing.
