Skin and hair, in a gentle curve whose lower end he couldn't see. A mons pubis with nothing jutting out from it. That was what looking in his pants showed to Alex - and it was, to put it one way, an interesting sight. He was going to experience, himself, one of the two new varieties of genitalia he'd chosen for people to be born with.
A few questions flashed through his mind in short order:
What were people going to think of his being a man with no penis? ... they would probably find it completely unremarkable, and certainly no less attractive than the alternative.
How was he going to have sex? His blank groin would have the same sensitivity as any other kind of genitalia - and any details beyond that, he might have first thought, would be someone else's problem to figure out.
Was this what he'd thought he was going to end up with? Absolutely not.
Was this what he'd hoped he was going to end up with? He wouldn't say, even to himself.
With these questions and others still running through his head, he resolved to at least get a better sense for himself of what he had - and the way in which it occurred to him to do so was to bring his pants all the way down and spread himself out on his bed, with his phone's camera then pointed at the mysterious underside of his crotch.
Snap.
What did his phone show him? His thighs, his stomach, the gently furred curve of his crotch, a recessed dimple the size of his fingertip on its underside and then his taint which ran between that dimple and his anus - just barely visible from the camera's point of view.
... it was kinda hot. This was a candid photo of some unfamiliar junk, and it took a moment for him still to even recognise that the junk which he was looking at belonged to him. What would he see himself doing with this junk, in the moment before realising it was his own? Rubbing it. Kissing it. Grinding against it. Perhaps that was the gist of what sex would entail for people equipped like he was.
(And what would it be like to press his crotch against someone's lower lips? To have the tip of someone's cock kiss the upper end of his taint? At this point, he could only wonder.)
... furthermore, looking down at himself now, was that a faint pink blush which he was starting to see in his crotch, barely noticeable through the gentle covering of his pubic hair, as he grew increasingly aroused? Well, blood flowing to a penis would make that penis hard; blood flowing to a vulva might make that vulva puffy; blood flowing to a crotch like his must make it blush.
Now that he knew what someone would be looking for, his next thought was about how easy it must be for someone to tell how turned-on he was right then.
