Just wondering but when my girlfriend masturbates she does not use a dildo or insert anything to bring herself to orgasm, she claims that she wants to remian tight for when we have sex? Is there any truth to this? We talked about getting a dildo for play and for her to use other than her vibrator, but she said she wont use it to masturbate. She is very happy wih her jimmyjane little something. But can useing a dildo or vibrator to masterbate with really affect her "tightness"?
