Main category for Dildos or Dongs – typically these are manual or non-vibrating probes for manual stimulation, however some may feature vibration or other functionality. Other than double-ended dildos, most will feature a suction cup base for sticking to smooth surfaces or mounting on a strap-on harness. Sub-categories are available for refinement. Penis shaped vibrators are kept under the Vibrators category because they are rarely strap-on compatible.
