All of the work you do in the therapy room is based on talking, however, you are also given homework to do with your partner in the privacy of your own home. Clients are often amazed at the progress they make and how well they get on, once they are over the initial nervousness at talking frankly about their sex life.
Many people come on their own to talk about personal issues around psychosexual issues. Although I recommend that couples work together on a relationship or sexual issue, I appreciate that one partner may refuse to attend and there are times when partners may benefit more from individual therapy.
Where there is a specific sexual disorder, I may suggest that you see your GP, to rule out or investigate any underlying medical conditions.
