Don't worry about it so much.. There are MANY girls out there -- some are TIGHT and some are LOOSE and MANY are in-between. From EXPERIENCE, let me tell you that a TIGHT pussy is just hype. Its best to have just medium tightness, as if she is TOO-tight then you can expect a headache...BELIEVE ME! As far as becoming LOOSE after getting popped...Let me tell you something young buck, NEITHER AGE NOR EXPERIENCE (TIMES SEX HAD) determine if a woman is tight or not. In fact the ONLY reason I am answering your post is because it oddly coincides with a recent personal experience of mine where I hooked up with an older woman (Aged 36). I expected her to be loose, naturally, but I was not put off. BOY WAS I SURPRISED...Before we had sex, she told me that she had not had sex in 8 years...I did not exactly believe her, as I was thinking "yeah right...girls always say either that or "im a virgin" when they are really not"...So I thought she was bluffing...DUDE.....DUUUUUUUUUUUUUUUUUDE.....DUUUUUUUUUUUUUUUUUUUUUUUUU(okay you get the point)de... This 36 year old chick was THE TIGHTEST thing I have ever been or TRIED to get into...I spent the first HOUR trying to get MY FINGER IN....It was not an overall fun experience....And when I was finally fucking her, my dick kinda hurt from the SHEER FORCE of the CONSTRICTION.... You will see much poon in your life: loose, tight, medium, stank, sweet, ugly, cute, roast-beef-looking, strawberry-shortcake...The more POON you see the more rounded a view you will adopt.
Good Luck and remember NEVER let a girl control you through PUSSY.
