Then don't have one. As a man, you have better options to prevent that than any woman could wish for. I'm talking about permanent birth control here. I've never heard of a man who had to beg his doctor for a vasectomy.

Also, men are not slurred, shamed, or gaslit by society and their peers for wanting to stay single. There's a expectation somewhat but no man gets called an old maid or threatened with cats and the gentleman bachelor stereotype is lauded by most people rather than looked down on or scorned.
