Trashy pics and instagram

So my boyfriend thinks that I overreact because he has a few instagrams that he follows that posts pictures of women in pretty provocative clothes like barely covers the vagina and see through shirts where you can see their nipples. He thinks that its just a picture and theres not a problem because its just a picture. I have expressed to him that I feel like that is extremely disrepectful towards me for him to follow those pages because the only woman he should be looking at at all in any way like that is myself. So seriously is it just me or doea anyone else find that disrespectful.
