When did you guys have sex for the first time after birth?

I am only a week postpartum and I am not planning to have sex yet, but really really want to. I had an easy delivery and did not tear. I am recovering really well and I have no soreness. I was only swollen about two days. I'm not going to have sex now, but I seen people saying their doctor said it was okay at 3 weeks. Did your doctors okay it then? I'm going to ask my doctor at my visit later, but just wanted some insight.
