Are the hairs further down where your hairline used to be? It really depends where your hairline was vs where it is now because your hair line is still in great shape.
It is natural for temples to go back, especially for white and asian men at your age. If you think it is a problem and you have family history of balding then you can look into intense temple massage and something like Minoxidil with a dermaroller. Or if you prefer, you can start Finasteride. Your hair looks good to me...any top/crown thinning?
