You think about how you'll manage in this world. If everyone is like this then you wont be seen as a freak or anything, but just think of how much you'll miss your dick. Without a dick you wont be able to jerk off or have sex ever, it feels so frustrating and empty without then there, and it seems you'll still have the desire to fuck people even without a dick.
Thinking about that you look out your window, except for a few buildings the city looks the same. Humans are still humans here, with the same basic psychology and everything. People must still want to fuck eachother even if they don't have the organs to do it.
Looking up porn you see that porn at least still very much exists. There's a lot of images of people nude, there's no boobs or anything but you're still turned on by seeing them. It's weird to be turned on but have no erection, it feels so wrong.
As you look more you see that people do have 'sex' in a way. They tend to just hump eachother and rub their genitalless crotches together, there's also a lot of people rubbing and massaging eachother in the nude. When you go onto fetish sites people seem to just be doing their fetish without the sex. People definitely want to fuck in this universe, but actual pleasurable bits don't seem to be possible. As for how you'll masturbate it seems people just rub their own bodies or hump things.
This all seems so frustrating, it's going to suck not being able to cum like you used to. But at least they don't have nothing.
