Genuine Adult Product Site, Positive or Negative for Links?

[EAOM]

We have client that have a non spam site that sells genuine adult products, that include penis pills and penis enlargement products.

My worry is that as these products are often associated with spam and link from this site my have a negative impact if Google et al view them as spam, should i consider no-following these links?

Are you asking if you should have a footer link to your firm since they're a client, or are you asking something else?
