Milking while having sex?

So I’ve been having a lot of trouble with my milk production... I had my baby 4 weeks ago today and I thought I was completely dried up... Until last night. I know nothing is supposed to go into the vagina for 6 weeks after birth but me and my SO couldnt help ourselves. About 2 minutes in I start pouring out milk and hes loving it starts squeezing my boobs and its just squirting out, I’ve never gotten that much in one sitting even when I was pumping every two hours. And now this morning I tried to get something out and only a little drop of clear milk. I don’t understand..?
