The SexKey question I can answer. It really is free, but I advise caution. Unless your ISP has a good junk mail filter, you may want to set up a dummy account to handle all the spam that joining SexKey will generate. Ads for Penis enlargement programmes, Viagra and Korean porn seem to be quite popular. Also, if you do join, don't forget to discontinue your free trial to Porn King or Penisville within the specified time period, or you will be billed. You do have to have a credit card to register, but it will not be billed. It is for age verification purposes only.
