It is always a bonus to have a larger penis, but getting over 8 inches can be quite scary and difficult for most women to handle.  This is due to the large size knocking against their cervix (the top of the vagina) which may cause bleeding.  

However, with some foreplay techniques, you can still enter a girl comfortably with size that big. Dr. Newman K. Lin of the Lin Institute, a research center for multiple sexual orgasms, has provided us with this multiple-step approach to cope with the above.
 

Step 1 – Massage

First, massage the labia majors, groins, pubis and clitoral base to relax the muscle around the vagina to get it ready for penetration.  If it is not working, then apply a light Finger Pliers massage to the G-spot and Clitoral shaft and turn it around to 11 and 1 o'clock position. This helps to relax the vaginal muscle and tenting expansion.

Step 2 - Penetration

Now it is ready for penetration, which is divided into 3 steps:

A. Shallow Penetration
Do not thrust in hard at a go.  Instead, start off with a slow, shallow penetration into the first 1/3 of the vagina. And simultaneously, give light gentle strokes on the G-spot and kiss each other for about 3 minutes.

B. Moderate Penetration
Next, engage in moderate penetration to test the vaginal flexibility and relaxation with a light stroke.

C. Deep Penetration
If there is no pain from moderate penetration, it’s time to give deep penetration.
 

Step 3 – Screwing

Next, use Screwing Technique and Kiss the cervix with the glans penis to avoid thrusting hard.  In the Chinese sexual bible “Su-Nui Ching”, screwing is the essence in sex as it helps to massage the vagina and penis.

Depending on who the driver is, there are two screwing methods.  If the female is the driver, she sits on his legs and turns her upper body right and left occasionally or uses her hip to rotate. While if the male is the driver, with the female will lying down, he can stand up or knee down to get the job done.

By doing so, it stimulates the brain to increase the testosterone level.  This in turn expands the vagina in length and width which makes it ready for heavy stroking or thrusting.

Screwing will not only gives you sexual enjoyment, it provides you other benefits which include boosting your sexual energy, strengthening penis erections and increasing in vagina lubrication. Furthermore, screwing each other for 10 to 30 minutes every morning has been proven to be an alternative to doing morning exercises workout.
