You probably weren't using them right. Certain kinds you put behind both your penis and testicles. These were probably that kind.

You need the instructions on the packaging for your package ;)

Please, tell us that you don't know how to properly use a **** ring. It goes around the base of the penis and the balls. The balls must come through the ring first (you should be soft when putting it on).

from experience, bigger is never better. some assume the size is all she needs n dont bother to learn how to use it for pleasure

OP, your gf might have been laughing out of nervousness. A lot of people do and I'm sure your gf is with you because she likes you not because of your penis size.

Since she's laughing already, perform a 3 ring circus with your little polecat jumping threw the hoops. I've saw those before and they are immensely entertaining.

#60-it doesn't say how she reacted to it

Her reaction was to laugh. But that's OK OP it doesn't seem she cares if its short of her expectations

You know it goes around the penis and the balls right?

Looks like you've got a wee problem....
