Cystitis symptoms: what they mean and when to see a doctor
Burning, urgency, cloudy urine — what each sign means, which symptoms need a doctor today and what you can do at home.
Why cystitis follows intimacy — and the simple routine that helps
For many women, cystitis follows intimacy with frustrating regularity. The reason is mechanical, not a matter of hygiene — and a few simple habits help a lot.
Why intimacy can trigger cystitis
During sex, movement can push bacteria from the skin and the area around the anus towards the urethra. Because the female urethra is short, they reach the bladder easily. It is so common after a new relationship or a holiday that it is nicknamed “honeymoon cystitis”.
Before sex
- Drink a glass of water an hour before.
- Both partners wash the genital area with plain water.
- Use enough lubrication if you feel dry — friction irritates the urethra.
After sex
- Pass urine within about 15–30 minutes.
- Rinse with plain water if you like — no scented products.
- Drink another glass of water.
Many women who know their pattern add a daily supplement routine with cranberry and D-mannose, especially during periods when intimacy is more frequent — holidays, a new relationship.
Cystobact fits this routine with three capsules a day and water.
Contraception and cystitis
Spermicides and diaphragms are associated with more urinary infections in some women, because they change the vaginal flora or press on the urethra. If you notice a link, ask your doctor about alternatives.
Menopause and intimacy
After menopause, lower oestrogen levels make the tissues thinner and drier, so intimacy can irritate more easily. Lubricants help, and doctors sometimes recommend local vaginal oestrogen — see our menopause guide.

Frequently asked questions
How soon after sex should I pee?
As soon as is comfortable — ideally within half an hour.
Can my partner pass cystitis to me?
Cystitis is not a sexually transmitted infection. The bacteria usually come from your own body; sex just moves them.
Should my partner be treated?
Usually not for ordinary cystitis. If an STI is possible, both partners should be tested.
