Case Study:  Factors affects vaginal tightness and sexual orgasm - prostaglandin E-1, prostaglandin E-2, Nitric Oxide, sympathetic beta nervous action, vaginal nervous sensitivity and penile size and firmness.
Reader: 01/29/2006>
Hi Dr. Lin

I am 24 years old and i for couple of years now i have been obssesed with the size of my vagina. Sometimes its tight sometimes its not. I would really like to know what makes it to change time to time. And how can i was it inside especially after intercourse. I have had only 3 sex partners till now. It has been really upsetting me. How can i prevent it from getting bigger. And also my last question. Is it safe to have anal sex? What are the neggatives of it?

I really appreciate you taking time and reading this short email.

Looking forward to your answer.

Dr. Lin: 1/29/2006>Similar to the penile erection and size, your vaginal tightness/size mainly changes with the vaginal tissue erectile mechanism controlled by the prostaglandin E-1 level, parasympathetic Nitric Oxide and the sympathetic beta nervous activities.

The mechanism is positively affected by the neurotransmitters and androgen hormones (DHEA, androstenedione, testosterone and DHT with an optimal range of estrogen and progesterone, but negatively by excessive and insufficient estrogen and progesterone. Your hormone level changes day by day in the monthly cycle and time by time in 24 hours
During your luteal phase where your progesterone level is too high to produce prostaglandin E-1 and Nitric Oxide, when you are too tired or exhausted to trigger Nitric Oxide release or prostaglandin E-1 production but enhancing prostaglandin E-2 release, or when you are over-excited for excessive prostaglandin E-2 and estrogen elevation, your vagina becomes too loose.
You can take Heat Tea or ViaPal-hGH-C (3-016) for a consistence of vaginal tightness.
When your vagina is too loose or his erection is too weak to let him feel good, you or he may want to try anal sex, but anal sex won't solve your vagina tightness or his erectile disorder.
For anal sex, please read
For his erectile disorder, he will need ViaPal-hGH-J if he is under 30, or ViaPal-hGH-P if he is older than 30.
Please Note that the vaginal tightness is a relative feeling to the penile size and firmness and it is not an absolute measure.
