Okay this sounds like some broscience i believe but I was always wondering why all the men's photos online look like they are either dead sad or depressed.

while women on the other side always look happy, or like their lives are good, or alive.

It could be either that we men have shit lifes comparing to women

OR

It could also be that men masturbate everyday while women dont (My assumption, women get more horny from your behavior and personality combined with visuals than just visuals (like on porn)).

Could it be that?
