The distance between your ischial tuberosities is very small. So I highly doubt your saddle is too narrow. I would think it is more likely that your saddle is too soft, and thus your ischial tuberosities are sinking in and pressure is being put on you coccyx.

All that being said, the Giant Cypress is a comfort hybrid bike with a very relaxed and up right seating position. I assume by the fact that you just got a new bike and that you just signed up for this forum that you have not been on a bike in awhile. The fact that your ass is not used to riding could be to blame.
