Three different concerns that can overlap and need different questions.
Desire, firmness, and timing are distinct
Low libido means reduced interest in sex. Erectile dysfunction means trouble getting or keeping an erection. Premature ejaculation concerns ejaculation that happens sooner than wanted with poor control and distress.
Why the distinction matters
A man may want sex but have ED. Another may have normal erections but little interest. A third may have strong desire and erections but struggle with ejaculation timing. Each story points to a different first evaluation.
They can affect each other
Worry about erections can reduce desire. Fear of losing an erection may lead a man to rush intercourse. Low desire can make an erection less likely. The answer may involve more than one condition.
Questions to ask yourself
Do I want sex? Can I become erect? Can I maintain it? What happens with ejaculation? Is this new or lifelong? Is it distressing? Your answers help frame a more useful clinical conversation.

What should you do next?
Write down what changed, how long it has been happening, what medicines you take, and what else is going on in your health or relationships. Take that information to a qualified clinician if the problem is persistent, distressing, or unexplained. A good plan starts with understanding your actual situation.
