Sorry, I am not in the USA nor of USA origin and there is no intention of violating any code of decency involving juveniles using this figure.

Quote - Why would you want to show (educational?????) nude pictures of any male poser figure (with or without a penis) to small children?   In some of the US States that could find you facing criminal charges. 

Quote - Although I have no reason to - pardon - lop off the guy's gens (oww oww), I imagine if I had to do an educational type naked figure render for younger schoolkids, then yeah, a smooth neutered look might be less attention-grabbing that a hole.  Or use the underpants, but they'll still see the bulge.

So upshot of my take is - could be useful to have the gap "capped", for whenever.
