This, of course, is because men can become fathers no matter how old they are. They don't have the same "time limit" as women, whose bodies will stop being able to produce children at a certain point.
Thank you for sharing this, for pushing past your fear of judgment and worrying about what others will think. You can't "hurt anyone" - people are free to choose how they respond. You have a right to say how you feel and to share your experiences. Some will support you, others might not, but you can't please everyone. Worrying about those people is a waste of time.
I'm so sorry for all the suffering you've experienced. It's got to be so painful. Thank you for sharing your story.
