My boyfriend likes other girls IG photos...

i'm not sure if i'm overreacting so i want to get some advice. Me and this guy have been dating for maybe about 2 months, nothing TOO serious but i'm his girlfriend, he's my boyfriend etc. Everytime i go on IG i see he's liked TONS of girls photos.. naked modeling, regular girls and everything in between. Am i overreacting? i would love some imput and experiences of everyone else. (Added picture to show the volume of pictures in less than a day 🙄)
