There could be physical or psychological factors behind sexual dysfunction
Speaking to NHS Choices, Dr John Tomlinson of The Sexual Advice Association explained that sexual dysfunction in a man is when he's not able to perform properly in the bedroom.
"The main problem is being unable to get an erection," he said." It's much more common than people realise. In the 20-40 age group it affects around seven to eight per cent of men, in the 40-50 age group it affects 11 per cent. In the over-60s it affects 40 per cent, and more than half of men over 70."
Although it can be hard to pinpoint exactly why a man is struggling with impotence, Dr Tomlinson pointed out that there is a range of factors that could be causing this, both physical and psychological.
