I'm a 42-year-old who has been married for many years.

I AM emailing in desperation, as a middle-aged man recently diagnosed with prostate cancer.

I understand you are dedicating the whole month of September to prostate cancer and sexual health.

DEAR Dr G, I am in my mid-50s and lost my wife during the first wave of Covid five years ago. I only began dating again in recent years, and am now happily attached to a partner who is considerably younger than me. We are very compatible in both our lifestyle and sexual desires.

I understand you usually address sexual health issues. My concerns, however, are not strictly sexual, though I worry that the consequences of this disease may affect my sexual health.

Dear Dr G, I am in my late forties and have an urgent matter that needs your help.

I understand that your August articles have focused on the impact of ageing on sexual health.

My husband and I are both 56 years old and we have been married for nearly 28 years.

Dear Dr G, I have turned 60 and am a healthy chap who exercises and watches his diet regularly.

Dear Dr G, I am a 66-year-old man starting a new relationship. Despite entering my later years, I refuse to slow down and engage in my career and exercise regularly to stay healthy.

Infertility is defined as the inability of couples to conceive after one year or more of active sex without contraception.

Dear Dr G, I read with interest last week's article on the "reversal of misfortune in infertility". My wife and I do not have any fertility issues, but we are reconsidering our family planning and hope you can help.
