I have had some issues with pets (and my brothers to a much lesser extent), that have convinced me that I will never have kids.
This, however, leads to some serious problems when dating/having a relationship with people. I **always** make it very clear to people before starting to date them that:
- I don't want to have children (I also explain why)
- I don't want them to hope/expect me to change my mind
Most of the time, this means we just part ways as good friends before the dating even starts. But in other cases, people say they're fine with *both* points.
