Many straight people find that professional counselling helps them understand what has happened which in turn helps them to plan ahead in order to rebuild their lives. In the UK, Relate is well known for helping couples whose relationship is in difficulty. In addition, many counsellors across the country specialise in sexual orientation and/or relationship issues. Having said that, many counsellors won't have had any training in this topic and little, if any, practical experience. You may wish to quiz your counsellor on this. Firstly there are two websites that list counsellors in your area. The BASRTis a national charity for sexual and relationship therapy. Just click on the 'therapists' link at the top of their home page.
The Counselling Directory is a extensive network of UK counsellors and psychotherapists, with information on their training and experience, areas of counselling covered, their fees and contact details. You can choose from a variety of issues, and you can browse the list for counsellors who practice in your area.
