Why does my bf not like clicking pictures with me?

My bf (18m) and i (17f) have been dating for almost 3years and it has been on and off.

He doesn’t like clicking pictures I don’t fucking know why. He won’t let me click pictures of his but he had like n no of pictures of mine. We barely have pictures together 😞 which is sad.

I don’t think so he is insecure of anything cuz like he is handsome as fuck. But he just doesn’t like clicking pictures let it be solo or with me but with his friends he is always clicking pictures.

Once I asked him to send me his picture and he sent me his back pic😭.
He is a gym guy so he keeps on sending me his biceps,abs and what not but not his face.

I am in my luteal phase so ignore my yapping. But please comment and tell if all guys are like this or is it just mine.😕
