Seeking Advice: When is the Right Time to Tell a Partner About Personal Health Issues

Hey everyone, I’m facing a tough situation and could use some advice. I have some personal health concerns, including erection problems, a small penis, and possibly being infertile due to a high immotile sperm rate. I’m wondering when is the right time to share this information with a potential partner. My dilemma is whether I should: 1. Tell her before getting into a relationship (so we both have clarity before things get serious)? 2. In case of arranged marriage when is the right time? 3. Is there a “right time” to bring this up, or should it be shared immediately?
