TMI but I have a concern about breastfeeding

So this may seem crazy but I'm a little concerned about something. My breasts/nipples have always been extremely sensitive. I've always loved having them sucked and played with, sometimes I can even cum just by having them sucked and played with. I really want to breastfeed but what if it turns me on? I feel disgusting even thinking about that possibility, but I'm really worried. Or, what if breastfeeding makes my sensitivity go down and it doesn't turn me on anymore during those times with a guy when I want to? Has anyone else had this concern? What happened when you breastfed?
