When you are picturing your favorite men's penis in your mind, is it flaccid or erect?
Flaccid penises emit pee. Erect penises emit semen. I'm only interested in erect penises. That goes for my fantasies too.
Why would it be anything but erect?
Flaccid and hooded, soft so I can put my tongue inside the hood and lick the head. Then let it build to fully erect so I can force it down my throat.
Always erect. A flaccid penis is no good to me. It's like trying to get a marshmallow in a coin slot.
If I am imagining us at the beach - flaccid - we are nudists.
If I am thinking of us being in bed together then it will always be in its beautifully erect state.
