He realized that his girlfriend was coming over in only an hour. Even if he was dickless, he still needed to see her. He realized that he had wanted to fuck her for the first time, and now he didn't have the equipment to ever do that.
He got ready anyway. He still had something down there, even if it wasn't the part that he wanted.
Getting ready was mostly normal, accept for putting on his pants and underwear, which were both now fitted for his flat crotch. It felt really off to have everything so tight down there, with all of his clothing completely flush with his new crotch. It wasn't something he could have possibly felt when he had a dick, and it made it easy to feel the fact that he was dickless.
Having to piss sitting down was also weird, he wished he could have just stood up. It felt so weird having it come from a hole between his legs instead of his penis, and it was all just super uncomfortable and awkward.
Eventually he was ready to see his girlfriend. Just one question first, what does she have in her pants now?
