I never had the experience, but we all have heard the young, tight virgin stories.  So, I guess my thinking has always been that younger and newer means tighter.  No disrespect intended to any of the ladies out there.

Tight and loose are all VERY relative. A woman is actually "looser" when she's attracted to you vs when she's not. Also every ladies body is different, we don't all come out with the same exact vagina, some are larger, some are smaller. Sometimes having children can permanently change the "looseness" but not always, i know many guys who proclaim she's so tight, but she's had two kids vaginally.  

Health,  fitness, and kegal exercises....

How tight a woman is is based primarily on muscle tone. Meaning, if ya do your Kegel exercises you can be super tight at any age!

Guys agreed with the line: "you could drive a truck thru it".  I did not have any hands on experience with her.

All I can say is...I so agree!

... fisting. And a few minutes later are tight and sweet for a good fucking.  
Damn women are wonderful.

A girl is the way she is. Tight or loose is subjective to every guy. What's tight to one guy is loose to another.

And her ability to control it.  Younger women who don't do kegels could well be "looser".    

If you think of your asshole and all the use it gets put to throughout your life, does it get less tight because of it?

Well I'm a milf,  as you call it.. and I've never given birth ,  So  figure it out...It's For Me To Know , and You to Find Out.. Wink

Anal sex can most definitely lead to anal incontinence in both men and women.

which made it an even worse analogy if he wants to compare shit coming "out of" one's asshole to having dicks "going into" a pussy.

...taken a big, fat, hard dump and had to push and breathe like you were in a Lamaze class?  Don't tell me I don't know nuthin' about birthin' no babies!!!

Maybe we should ask Chicken Little after Ivy is done with him? lol

Before you take too many bows for the size of your dick stretching some vayjayjay, in reality it stretches to accommodate child birth -- whose heads typically have a girth of 13.5 inches.

yes, a baby will come out, but can you imagine trying to put one back in again? lol

When you can pass an avocado through your penis, then you can talk about child birth.

But speaking of passing an avocado, I have heard of some STD's that will make your piss look like guacamole, only it stinks worse. lol

thanks for that image . Really made my day. I may never eat guacamole again.

I bet you skipped that class in school. I am sure every adult knows that the vagina is a muscle. The tightness will depend on the person's muscle tone.
