"A climax of sexual excitement". That is called an "orgasm". Some say "it's like a wave of pleasure coming from down there and bringing me up to an explosion." Or "my muscles shrink and tingle everywhere. I cannot help but to lean backward and get into spasms with spectacular sensation." Or "A blackout. I cannot move for a while." Or "It's literally 'COMING'. Slowly from inside of my body, and springing out with my peak cry."
Sounds like something big and utterly desirable.
First of all, it is not an easy thing for women to get an orgasm. 50% of women have never experienced orgasm with penetration. So it's quite a normal thing if you have not yet go there. On the other hand, women can get an orgasm with clitoral stimulation quite easily. Is there any difference?
Level of Orgasms
Let's see the level of orgasms. It is said that a penetration orgasm is about 2 - 3 times more intense than a clitoral orgasm. And the cervix orgasm is even more, and some women will faint from this powerful orgasm. However, you need to develop your body with your partner until you reach to those orgasms. (Please note that the orgasm is totally depends on each woman and there's no such thing as a benchmark. These are only references from past research.)
Find your pleasure zone
First, you need to know where those erogenous zones are located. If you cannot tell, your partner will never know (unless he's a sex master). And if you can tell, you will never think you are sexually insensible.
The Clitoris would be easy to find since it is located outside of the vagina and can be reached by yourself without difficulties.
To find it, you can pull the labia upwards to open it. Then you will see there's a small skin hood in the middle. The clitoris is usually hidden under this thin skin hood. Try to stimulate this point with your finger, a vibrator or even a shower. DO NOT touch roughly as it's just hurting. Slowly and gently. If the friction hurts you, use a water-based lubricant or your own secretion. This is the most sensitive part of the entire female body and it responds to sexual arousal by filling with blood. So from anatomical and orgasm point of view, it is usually considered as the female equivalent of the head of the penis. Clitoral orgasm is a basic and a starting line for further stages. Try to aim at this first.
