What's usually going on
Erections depend on blood flow, nerves, hormones and how you are feeling. Stress, poor sleep, alcohol, some medicines and conditions like high blood pressure or diabetes can all get in the way.
Because the same blood vessels run everywhere, it is also worth a proper look at your general health. The conversation is the hard part, so we have made it a questionnaire.
Premature ejaculation means coming sooner than you or your partner would like, more often than not. It is one of the most common sexual problems men have, at any age.
Anxiety, relationship stress and sensitivity all play a part, and sometimes another health condition. Talking it through is often the first step, and a clinician can explain the options, including treatment where it is suitable.
