Sexual Aversion Disorder

This is not a juicy story. But let me share it here for your thoughts. I have a friend who confided me about their marital problem. They have been married for almost a year, yet their marriage was not consummated or in short, they never had sexual penetration. As he further disclosed, his wife's previous marriage was annulled due to psychological incapacity, based on that sexual disorder as one of the grounds. Now he is pondering whether to pursue a nullity of marriage case. With this concern, i advised him to first seek from a mental and sexual health professional so they could exhaust all the possible means to address their marital problem. He already messaged Dr. Rica through her IG but no response from her since she sent a message a year ago. As such, can anyone please recommend a clinical psychiatrist or health peofessional with experience along with this problem? If you know one, would you please share the name, clinic address, areas of specialization, your experience with him/her, and other relevant info. Your responses are highly appreciated.
