Frustration
Being cut is frustrating. Waking up to my dick straining and rubbing against my bedsheets with my balls pulled up tight. I instinctively reach down but there is no mobile skin to play with so I just rub my dick through the bedsheets hoping to feel something but it's futile as all the good parts have been removed.
I contemplate wether it's worth the effort to get lube, find the right porn and then deal with the clean up. I think about how it doesn't really feel like much in the beginning and I'll just have to rub harder and harder to feel something and it'll take me forever to cum. When I finally do cum it's not really going to feel all that satisfying. It's more like the feeling of pressure and fulness is gone.
I think to myself it's just not worth trying today and feel jelously and resentment towards all the intact people that can just have a quickie whenever they want.
