I think Kimberly is a sex addict

Few reason why I think this.
During the Winston impersonation of her, he put a lot of focus on her being horny. Has she talked about this inside a lot more than we have been shown.
Her profile says she likes to explore her sexuality.
She says she doesn't have commitments and doesn't feel comfortable talking about this subject.
During a conversation with Danielle she said she didn't want anything to happen, but not sure if she could avoid it, a couple of weeks ago.
A twitter message said something like "love is being free".
She has sex on Big Brother and gets fingered on Big Brother.
There are plenty other little things too
