Case Title:  He said ' I stop doing masturbation/PC flex as much and did a lot of the butt exercise and now I m lasting 2hrs.'; On natural vaginal lubrication for sexual orgasm.
Reader: 5/25/2003>
Thank you for the advice when I came over to your house I stop doing masturbation/PC flex as much and did a lot of the butt exercise and now I m lasting 2hrs.
Thanks a lot
Dr. Lin: 5/26/2003>
good jobs!

Reader: 5/26/2003>My girlfriend Jen is so happy I stopped masterbating so much and I have been practicing the butt excercises.It actually made my butt a lot firmer she likes it a lot.my penis stays very hard thru foreplay and she likes to grab onto to my butt as I thrust into her vagina for an hour or so.Thank you so much.She likes anal sex a lot is that ok and do I need a lot of lube for my penis?
Dr. Lin: 5/26/2003> 

Her vagina is supposed to produce the natural lubricant upon sexual arousal. 
If not, she needs our products to restore her vagina natural lubrication production function.
Heat Tea or Viapal-hGH-J or -C can help. 

Reader: 5/28/2003>
She was on antibiotics and now the medicine is done for her cold so maybe that dried her vagina up can that happen?

We had sex for 2 hours today thats including foreplay it seems that her vagina was a lot wetter the hole time also it seems loser.My penis is around 7 1/2 inches long and her vagina is usually really tight but we have had longer sex lately lasting about 2hrs.I can thrust my penis all the in her without it being to tight is that normal for her vagina to stretch?

Dr. Lin: 5/28/2003>
Yes. Antibiotic also causes yeast infection.
I think that her vaginal wetness lets you feel looser due to less friction.
When her vagina is tenting up due to sexual arousal, you will feel her vaginal is deeper.
There are two spots let you feel her vaginal tightness: one is the vaginal orifice and the other is the Epicenter, the gap between her bladder and cervix. Beside these two spots, the middle section of the vagina is hollow, about 2-3 inches diameter.
If your glans penis doesn't lock into the Epicenter gap, your glans penis feel nothing inside.
If your galns penis penetrates into her Epicenter gap and she contracts her low abdomen muscle, you will feel your glans penis being tightly gripped and sucked up.
At the same time, if she knows how to contract her vaginal orifice and PC muscle to tighten up the low section of your penile shaft, you will feel your entire penis being tightly sucked and gripped by her vagina.
Making love in this way is called sexual ChiKong intercourse which will help tighten the entire vaginal muscles too.
