Sexual difficulties are surprisingly common.  Research suggests that more than half of us will experience a problem at some point.  It might be the impact of children, ageing, work, illness, disability or the use of pornography.  In a long term relationship it might be over-familiarity, lack of motivation, or just growing apart.  

Sometimes, things from our past such as what we learnt (or didn't learn) about sex, emotional difficulties, abuse or trauma can affect how we are sexually now - despite our best efforts for things to be different.
