If he's relaxed, the dick will lie more relaxed too. If you don't have a dick you can probably work out if the dick should be tensing or relaxed by getting into the position you want to draw. If your pelvic muscles or lower abs are doing a little work to keep you upright, the dick will be more like 2. If you are fully relaxed, the dick will be more like 1 unless the character clenches on purpose or holds it.
That's only for the hard dick though. If he's soft or only has a mild chub, it'll either lie back against the body, often turned to one side towards the thigh crease, or it might flop downwards. Depends on how tight and high the balls are and if his legs are pressed together or separated. Also even the smallest flaccid dick doesn't look like a deflated balloon. There's more three dimensionality to it, even if there is a lot of foreskin. You can tell there's something more solid inside basically.
