Hi, the penis is often connected with fertitlity, power or agression and houses very often represent your self with the different rooms representing different aspects of your mind/soul. The deeper down rooms often signify your deeper, darker thoughts, while rooms at the top like the attic often represent your higher spiritual thinking. Other rooms can be more literal, like the kitchen can represent nuturing and sustanance and so on.
Anyway, I wonder if you are going through any kind of power struggles in your mind at the moment, if there is something connected to this in your life? Dreaming about being a man or a woman, or having male or female sexual organs, rarely means what one might suppose it would in a waking life context and is fairly common.
