Still lactating?! 😱😰

I haven't breast fed in over 3 months. I thought my supply had dried up since it's been so long.

Anyway, kinda embarrassing...

I just recently left my husband and I stayed the night with my friend.

We were drinking a little and eventually clothes came off.

He started sucking on my breasts, stopped, looked at me and asked if I was still lactating.

I was so embarrassed. I apologized multiple times. Still do actually. Even though he said he doesn't mind it (he has 2 daughters with his ex, so it was nothing new to him).

I just don't understand how I'm still producing? How can I dry it completely up?
