The fact that you characterize parenthood as a "side-quest" confirms that you probably shouldn't become a parent.
I'm 42 and have simply never felt the desire to be a parent. Never felt a biological need to reproduce. Don't get me wrong, I have a libido, but never wanted a baby to come from it.
I can rave for hours about how great the DINK life is. A sibling comment talked about the logistics of traveling on vacation with kids. It's amazing to not have to deal with any of that.
If you’re not looking forward to it being the main event, you probably should just skip it all together and save yourself the disappointment.
Parenting is extremely undervalued in modern society.
And yet they reproduce anyway.
