ABR (adult breastfeeding relationship) does anyone have any thoughts on this or does it?

Does anyone participate in adult breastfeeding relationship? Or have any thoughts on the matter? My husband and I have a great sex life and normally have sex at least once a day. My 14 month old is weaned now as he just stopped cold turkey one day. A couple of months later I'm still producing a small amount of milk. I have always enjoyed getting my breasts sucked but didn't do it while I was feeding. My husband mentioned a couple of weeks ago that I was still producing milk and I asked if it bothered him and he said no. I really enjoy him doing it but am frightened to actually ask him to do it. Any advice would be great
