The next morning you wake up and walk to the bathroom still a bit tired, for some reason you don't have morning wood today. Before brushing your teeth as you usually do you realize you need to use the bathroom. As you walk over to the toilet and reach for your dick you suddenly realize that it isn't there. You examine your body to find that you lack any form of genitalia, just smooth unbroken skin leading from you waist to your anus, there is a small hole in between your legs for letting out urine.
The novelty of not having a penis overrides to shock. Your brain remembers in being there but there's nothing hanging there, and nothing protruding. You wave your hand in front of your crotch and feel the area where you dick used to be, rubbing your pelvis up and down to experience the nothingness.
Getting worried about yourself you look at yourself in the mirror for any other changes. You still recognize yourself, same general face shape, but much more androgenous, like if you had never gone through puberty. Someone could still tell its you, but if they didn't know you they wouldn't know if you're male or female.
Suddenly you hear Brooke calling you. Normally she calls you in for morning sex but that might have some physical issues. The though of her naked makes you horny but you get no physical response from you body, The feeling of being mentally aroused but unable to be physically aroused is quite frustrating.
