Q I’m 25-years-old and I have been having regular wet dreams since my early teenage years. I always assumed that these would stop as I got older and I can’t understand why they haven’t. What can I do to stop this happening, and is there a reason for it?
David, Hemel Hempstead

A There is nothing wrong with having wet dreams at all. If you enjoy a normal sex life, have no sexual dysfunctions and can get an erection and ejaculate normally, then there is no need to do anything about them. Wet dreams are generally more common during the teenage years because of surging hormone levels, particularly testosterone, driving erections and erotic dreams, which can lead to orgasm. For many guys, these settle down as they get older, but some men continue having wet dreams into later life. It’s completely normal.

Q I self-harmed as a teenager and have scarring on my wrists and lower arms. I am no longer harming, but I don’t feel as if I can move on while the scars are visible because I feel like people get the wrong impression of me when they see them. Is there any way I can get rid of them?
Anthony, Bristol

A First of all, well done for getting over your self-harming issues. Because your scars are now several years old, they are unlikely to fade any further, and you are left with two main options. One is laser treatment on the scar tissue to reduce its appearance. This can have mixed results, and may have to be funded privately. Another option is surgery to remove the scarred skin – you will be left with one surgical line, instead of numerous slashes, but this really depends on the extent of the area of skin involved. This could also be costly as the NHS may not pay for it. You will never completely get rid of the scars, but you can reduce their appearance.

Q When I step from dim light into bright sunshine it causes me to sneeze. I don’t know anyone else who this happens to, and my friends make fun of me for it. Why does this happen to me and no-one else?
Mark, Dover

A Actually, this does happen to plenty of other people – a quarter of the population, in fact. It is known as the photic sneeze refl ex, and is an autosomal dominant hereditary trait which causes sneezing when suddenly exposed to bright light. It also has a much more complicated name: the Autosomal dominant Compelling Helio-Ophthalmic Outburst syndrome, or ACHOO for short! I kid you not. It is all due to an old evolutionary refl ex, which is there to protect your eyes from sudden bright light. The sudden constriction of your pupils and the closing of your eyes leads to sneezing. There’s nothing you can do about it, but there’s nothing wrong with you. In fact, it happens to me too!
