Show your love. Experts recommend beginning the conversation by explaining that you love your partner and want them to take care of themselves so that they live a long and comfortable life with you. Start and end your sentences with, "I love you."
Pick the right time and place. If you're going to address erectile dysfunction, don't have the conversation in the bedroom when you both may be feeling vulnerable. Pick a neutral time and begin by explaining that you love him for who he is and not his physical performance. If you're concerned about how many times he got up to pee during the football game, don't bring it up in front of his buddies. Wait till your home and alone. And don't talk about memory loss just as he's looking for the keys. Wait till he isn't distracted and won't feel like you are calling him out.
Make a plan together. After you listen to his concerns about the issue, explain that you want to work on it together and that the first step may be visiting a doctor to check for underlying health problems and get treatment.
Opening up is the first step. While a diagnosis may be scary in and of itself, remember that there are treatments, if not solutions, to all of these ailments and talking about it is the first step to feeling better.
