If you are referring to a flaccid penis that sort of points more forward than straight down, it could be a few things.
1. Cold temperature is causing the thin muscle lining the scrotum (dartos fascia) to contract, making the scrotum more spherical- this is pushing up against the bottom of your penis pushing it out. Warming everything up (such as after a hot shower), relaxes this muscle allowing the scrotum to drop down, which may allow your penis to drop straight down. The warmth will open the blood vessles up too, allowing for a better flaccid hang.
2. Tight ligaments. The ligament attached to the top of your penis may be tight/small which will sort of be holding it up/forward a bit. Stretching will - over time - lengthen this ligament and give you a better flaccid hang. Just be patient and consistent.
*3. If you are circumcised* - the cut was done unevenly with more skin remaining on the underside of your penis than on the dorsal/top side. This skin would act much like the small/tight ligament and pull the penis in closer and up/forward. Stretching the skin can help this if that is the case.
Those are all I can think of.
