We had our two quite close together (18 months), so for the first 4 or so years, it was just relentless.
It's hard to explain it. You have to do everything for them. Get them out of bed, feed them, clothe them, take them to the bathroom. Entertain them. Soothe them. Be present for them. They can't do anything alone, so it is just relentless. Add sleepless nights into the mix, and it can be very hard and thankless.
Mine are older now, and in the perfect small window of being much more self-sufficient, but without the worry of the teen years.
We are extremely lucky. Our DC are nice, well-behaved kids who get on well with each other, don't have any learning needs or behavioural issues, and they have nice friends. I have a fully on-board husband.
If just one of these things ^^ wasn't present, it would make life harder. If several of these things weren't present, life would be a struggle (to the extent of negatively impacting mental health) much of the time.
The thing is, you don't know what sort of hand you're going to be dealt, and much of it is down to dumb luck, much as we all might like to think we have superior parenting skills.
I would say - don't rush into it. Enjoy your 20s. There's the rest of your life for settling down and domesticity.
