The impact of female circumcision is a lot lower than that of male circumcision, but IMO both are genital mutilation.
As to dildos, Ezekiel 16:17 gets very close. Picking a few translations at random:
“Thou hast also taken thy fair jewels made of my gold and of my silver, which I had given thee, and [m]madest to thyself images of men, and didst commit whoredom with them,” (https://www.biblegateway.com/passage/?search=Ezekiel+16-17&v...)
“You also took the fine jewelry I gave you, the jewelry made of my gold and silver, and you made for yourself male idols and engaged in prostitution with them.” (https://www.biblegateway.com/passage/?search=Ezekiel%2016-17...)
“You also took your beautiful jewels of my gold and my silver that I had given you, and made for yourself male images, and with them played the whore” (https://www.biblegateway.com/passage/?search=Ezekiel+16-17&v...)
> You also took the fine jewelry I gave you, the jewelry made of my gold and silver, and you made for yourself male idols and engaged in prostitution with them.

Genital mutilation:
> Saul replied, “Say to David, ‘The king wants no other price for the bride than a hundred Philistine foreskins, to take revenge on his enemies.’” Saul’s plan was to have David fall by the hands of the Philistines.
Ummm... circumcision is pretty central.
> This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised.
The negative example aspect is important, because it conveys the intent that such material is included (and mind that even Bibles that contain pictures in them, don't depict those scenes). Rather than something to "get off on", as pornographic material does, it is something to feel disgusted by and thus be dissuaded from engaging in such practice.
