Why do boyfriends follow bikini girls?

Hey everyone, why do boyfriends follow girls that show off their bodies on instagram? it truly hurts my feelings. My boyfriend once told me that there’s no feelings at all to these girls and how he doesn’t “look” at them. So if you don’t “look” why do you have it? :( i’ve been so insecure for years about it and i thought i was the issue but now i truly think that im insecure because of him following so many girls and doesn’t care how or what i think.
