Sexual wellbeing is not a separate thing from general health. It sits downstream of hormones, sleep, cardiovascular fitness, mental health, medication and the state of a relationship — which is why a change in it is so often the first thing people notice when something else has shifted.
These guides treat it that way: as something measurable, explainable and usually improvable, written for adults in their forties, fifties and beyond. No euphemism, no hype, and no pretending a product fixes a medical problem.
Start here
Low libido
Why desire drops — hormonal, psychological, relational and medication causes — and how to work out which one applies to you.
Erectile dysfunction
What causes it, why it can be an early warning sign for your heart, and when it needs a GP rather than a workaround.
Sexual performance anxiety
The self-fulfilling loop of worrying about sex during sex, and what actually breaks it.
Menopause, perimenopause and sex
What oestrogen decline does to desire, arousal and comfort — and what can be done about each.
Painful sex and vaginal dryness
Why sex becomes uncomfortable, why it rarely resolves on its own, and the treatments that work.
Prostate health and sex
How the prostate affects sexual function, what PSA does and does not tell you, and when to test.
Why we keep pointing at bloodwork
A great deal of sexual-health advice is guesswork dressed up as confidence. Low testosterone, an underactive thyroid, iron deficiency and the hormonal shifts of perimenopause all produce overlapping symptoms — low desire, fatigue, low mood, poor recovery — and you cannot tell them apart by how you feel.
A blood test converts that into numbers you can act on and re-test against later. It is not a diagnosis, and it does not replace a clinician; it is access to your own data.
Hormone and fertility blood tests
At-home tests analysed by a UKAS-accredited UK laboratory, in discreet plain packaging. Testosterone, male and female hormones, PSA and fertility panels.

Each one is written to stand alone, so start with whichever describes your situation. They cross-link where topics genuinely overlap — erectile difficulties and performance anxiety feed each other, and menopause and painful sex are frequently the same conversation.
Where the responsible answer is "see a doctor", we say so plainly rather than selling you something instead.
Common questions
Is sexual wellbeing really a health issue?
Yes. Sexual function depends on circulation, hormones, nerve function, mental health and medication, so a change in it frequently reflects a change in general health. Erectile dysfunction in particular is recognised as an early marker of cardiovascular disease, which is why it is worth investigating rather than working around.
Do I need a blood test, or should I see my GP first?
If you have a symptom that is new, persistent or worrying you, see your GP first — a test result is not a diagnosis. Testing is most useful when you want your own baseline data, or something to bring to a consultation.
Are these guides for men or women?
Both. Some topics are sex-specific — erectile dysfunction, prostate health, menopause — and are written as such. Low libido and performance anxiety affect everyone and are written for both.
Is any of this a substitute for medical advice?
No. These are general health information, written to help you understand what is happening and ask better questions. Diagnosis and treatment are for a qualified clinician.
