so i have been using the Bathmate once a day for about 5 days now with no problems. but today when i used it, the suction wouldnt work. when i push it to my body, it sucks on for the first pump but then if i pump after that, it loses its suction. could someone please tell me whats wrong? is there a way i could send it back to Bathmate and get a refund or a replacement model? i have the x40 by the way. im a college student and i spent all of the extra money i had on this. please help when you can, thanks.
