Beckley block your ex. Stop listening to him. If your family judges, you stop sharing with them. Be careful having sex without protection, check for STDs. Your family doesn’t need to believe you because frankly none of it is their business.

Also I’d try to discuss with your therapist difference between dating and simply having sex without attachment. Nothing wrong with casual sex but I am not sure why you are referring to it as dating. Again make sure you practice safe sex and keep these things private
