I want to get my girlfriend a realistic dildo and I feel like a suction cup would be fun. Do you feel that suction cups add much to the fun of the toy? and are there any negatives to them?
Depends on the person and how they use them. I have found them useless for me because I can never get it positioned right so I can have doggy style alone with my toy in the shower. That is personally me though an I am short so that doesn't help me much. I have been able to stick it to the edge of the tub and ride it but not as much fun.
