No she doesn't need to do hardcore. But I wouldn't mind some more nudity or a little bit of every now and again toy play. Beyond that, keep the guys out of the galleries. It will only cheapen her and probably even drive away many of her fans.
Some people like solo girls. And even if she were to do hardcore, it'd be a month before people start crying for anal. Than everything else under the sun after that. And before you know it she will be lost in the vault of freeones classy model to your basic internet skank (not that there is anything wrong with the internet skanks, but come on, you know what I mean)
She is fine where she is. Still pretty. Classy. Beautiful.
But, and I will say it as it has been said many times before, only qualm I have with her is her doing what she did to her nipples. But whatever, it obviously isn't pushing me away from enjoying her galleries, along with the others that do not like them like that. So, 'nuff said.
