Well being that i seriously doubt you would intentionally damage me or "Knock" it out..after reading your reviews sure why not..by the way..i have no cervix to damage but i do have a really tight pussy that i dont want stretched out..the gents will attest to that i think :-)
This is morbidly funny.
and yes gents..there is such a thing as too big.
if it's huge....it hurts....and in my experience most guys that big like to hit it hard...that is absolutely NO fun.....and if it's that big....a girl can't take it all the way in her mouth....vagina or ass...so I feel sorry for those guys...can't be as good as feeling the entire length enveloped in velvety warmth and wetness.
