I have a cousin who is a sex therapist, she referred me to a friend of hers?

Awkward? I imagine you're feeling concerned about a potential breach of confidentiality if you were to see your cousin's friend. That's natural. If you decide to see this person, you should definitely talk about your concern regarding confidentiality. If you're preoccupied with that concern during your therapy, it will constrict what you are willing to talk about, and that could be counterproductive.
