Taking pictures with pierced nipples

I stopped wearing a bra about 7 years ago. Got my nipples pierced about a year later. My bf never cared if I took pictures and posted them or anything. Never cared that I didn’t wear bras out in public. Then I got pregnant with my 2nd kid. Took the jewelry out after having him because I was breastfeeding. 3 years later.. I got them re pierced. (Still never wear bras) all of a sudden it’s a problem that I don’t wear them. I just changed my fb profile pic (not wearing a bra) and he literally just started blowing my phone up calling me trashy. wtf? He knows I hate wearing them and just because I changed my profile pic doesn’t mean I’m looking for attention. It’s just hurtful because I KNOW he looks at other girls and they show WAY MORE THAN I DO.
