Eh.. I honestly see no problem with genital items, genetalia on models or pictures, etc. Because if you think about it... if you've owned a male dog or a cat, you've seen it before. It's natural, so.. I don't think it's really a big deal.
It kinda annoys me when people flip out when they see a picture or model with genitals or a penis.(Yes, I am not afraid to say the word because it is the scientific name, it's not that bad so I'd like to ask that you don't jump at me for it. |D)
I've seen people flip out all like, "OMG IT HAS A PENIS!" and I'm just sitting there like, "Really? -.-"
It's just natural parts that you see every day on real dogs and cats, so why should it be a problem on the internet in item packs, on models, in pictures, whatever? |D
