Sex therapy is a subset of marriage and family therapy that focuses on improving sexual dysfunctions and intimacy issues. If you have never heard of it before and are curious about how it can help you, you'll want to tune into this episode!
Examples of intimacy issues:
partners have different sex drive/libido, inability to communicate about sex, vaginismus (sexual pain), anorgasmia (not able to orgasm), arousal issues, premature ejaculation, delayed ejaculation, sexual trauma, mixed orientation relationships (one partner may be heterosexual while the other is queer or asexual), etc.
