Fear of the birds and bees

Son (while being tucked into bed): Mom, I’ve decided I am not going to get married.
Me: Great thought “sonshine,” why not?
Son: Because you know that thing you have to do to have babies?
Me (hesitantly): Yes...
Son: Well, I would be scared to do that with my wife so I think I won’t get married.
Me (dumbfounded): Okay
Son continues: Mom, were YOU scared to do that thing that makes babies (he has obviously forgotten the word “sex”)?
Me (trying to sound even keeled): Ahm, no.
Son: Ahhh, I guess adults are a lot braver than children.
Me: Yes, I guess so.
