Hi, can I answer your health question? Please type your question here...
This guy I love tells me that I need to come clean about a secret porn life I have. I do not have sex with multiple people, nor have I ever. My question is, why does it make me so angry that he does not believe me? I want to throw sand in his eyes, because him not believing me emotionally hurts me that much. What is wrong with me?
