Nearly two thirds of men and women will experience sexual issues at some point during their lives.  Sexual issues may be influenced by cancer, sexual orientation, anxiety, an affair, sexual trauma, or lack of confidence.   Sex therapy is a specialized area of psychotherapy used to address and understand these issues.  It frequently goes hand-in-hand with marriage and couples counseling and commonly addresses a wealth of other issues that may be intertwined. While couples may choose to do therapy with their partner to examine the challenges within their situation, many individuals have a partner unwilling to engage in therapy, or choose to address their personal issues without being involved with a partner.
