Raymond says another common thing is men reporting they feel intimidated by the sexual confidence and demands of modern young women.

‘Women are now so empowered,’ says Raymond. ‘They feel they have as much right as men to dictate the pace sexually. We are not just talking about girls who would once have been seen as promiscuous.

‘These days a professional career woman who has been brought up in a culture of success wants to exercise that freedom and strength in her sex life, too.

‘In just one or two generations, there has been a turnaround. Before, it was always the expectation that the man was the predator. Now ladette culture has turned that on its head. Faced with this pressure, young men bring performance fears to the bedroom long before any sex takes place.’
