I want my partner(ish) to go through a pregnancy scare with me
I just want to be scared of pregnancy.
It's weird to me, when asked when I want kids
It is okay to be curious about how things like pregnancy scare feels, but you shouldn't want to have other people go through it, if it is not necessary. You will just make them feel bad for no reason.
I was wrong, I don't want to go through it.
Good, I am glad you have recognized your error and will not do this.
