Breastfeeding and modesty, opinions wanted

The other day I was nursing my infant on my couch, my SO came in with his friend and things just carried on as normal. After his friend left my partner was obviously upset with me because I didn't leave the room when his friend entered. It was supper time so I was cooking and to be honest I didn't even think of leaving the room or covering up because it's my house and I pay for it (we live together but I pay the rent, I lived here alone for many years so to me this is my house if that makes sense) if you can't deal with it leave... that's kind of my approach to things in my home.​I agreed in the future to leave the room when he brings people here and baby needs to eat. But it grates on me a bit that I should be expected to change my behaviour, feeding our 2 month old infant, to appease him. He is worried about his friend sexualizing me. I kind of think if his friend can't help but sexualize me while I'm feeding my baby then he doesn't need to come over.​I do cover up in public and in other peoples homes. My boobs weren't out, I had my shirt pulled down on one side and was using a nursing pillow and holding baby's hand. This is my home. I feel like babe and I should be comfortable to do as we please here.Is nursing really that big of a deal? via /r/Parenting http://bit.ly/2ReXvIS
