Word of advice: take your time before having kids. Enjoy your partner, go on dates, spend time together. Kids change everything. They'll drain your sleep, your strength, your partner and companion. And you can't fight it, because you'll love those kids more than anything in the world.
Marriage is never all smooth sailing. There will be romantic months when y'all go at it 3-4 times a day, and there will surely be months you barely get any in a week. That's the reality for most.
It has nothing to do with being sexually attracted or not. In fact, there will be days you'll be the one running from it.
Marriage is more than just coitus. It's more serious than that. And once you're responsible for little beings who 💯 depend on you, you’d then realize there's much more to life than your needs.
