Helpppp!!

My fiancé is telling me that he is having some problem. He's telling me that his dick is not working properly. He ised to use steroids before but then he stopped. After that he was on a treatment to start producing more sperm but for a couple of weeks he was using steroids at the same time. Last night he started crying to me and telling me he feels less of a man because of what's his body/mind is doing to him. I told him to stop stressing about it because it will make it worst. We used to have sex every day when he was using the steroids before he even said it. But now that his body is clean and we are trying to have a baby, his body is just changing. Going against him. He feels horrible as a man I'm sure you can imagine. He asked me to be patience with him and not to give up on him. I whisk I could buy him something or do something about it. We are trying to have a baby so we don't wanna take anything that it's going to affect the process of having a baby.
