Under no circumstances is this a "How have an orgasm, so if that is what your looking for then STOP, walk back the way you came in, and click a story I wrote. This is just a tool you can use to help you write your version of a female orgasm. Is it the only tool out there? Good grief, NO! Just my opinion on a subject I have written a few times and experienced too.
Many authors I have talked to are men. They can only imagine what a woman is feeling when she climaxes and then only if she shares it with him. A woman can only share what they are feeling if she can find the words that describe it. There are various types of orgasms. There are the ones that are quick and fast. There are short ones that last for a moment and are highly pleasurable, and then there are the mind-blowing, body-thrashing, pussy-numbing climaxes that make me feel as if I'm going to pass out.
Quick and fast climaxes are great. They tend to be raw and hurried, but very nice. In writing one of these I try to see what has led up to this point. Were my characters fighting? Were they in a dangerous situation just minutes before and now the adrenaline is pumping through their veins as well as their sexes?
The orgasms I write for those scenes are usually full of raw words. Lava. Heat. Crash. Slam. Coat. I try to imagine colors also. Reds. Oranges. Golds. Yellows. Black. Silvers. They are all important and all can be used as the orgasm rips through your character.
Carol screamed as Mike's cock made one last plunge into her slick sex. The cliff fell away and her body slammed against the shores as her climax tore through her. Her eyes rolled, her back arched, and her muscles clenched his shaft. Rolling waves of heat coated her pussy. It rolled down to cover her lover's cock and as the white, hot nectar flowed thick from her sex, Carol knew she was his. He owned her and with every crashing wave that followed she continued to ride the tide that spontaneously forced his come to shoot out of him.
The second wave of Carol's climax brought red sheets of silk and she bit her lower lip, bruising the tender flesh. "Oh my God " she cried. Her fingers curled into the blanket and she felt as if she were hitting the rocky shores of a great ocean. Her body convulsed as she came until finally her breathing held and her body stiffened. "Fuck " she yelled and stilled.
In that example you can see the explosion, or at least I hope you can. It is a fast paced orgasm. It seers the character. She feels so much heat that her body is almost on fire. The colors help. They relate to how the heat of the moment is all consuming and bright. Words are like paint, you the writer, has to paint the picture with the color of black ink. You have to give your work dimension. If you don't, then how does the reader see what you want them to see?
Another orgasm is the virgin orgasm. Now realistically not many virgins will experience an orgasm, but a writer wants their character to have them. They can be written. They just have to be written with class and style. I'm not saying this is the only way, but to me a virgin having an orgasm the first time she has sex should be classy, even if it may not be realistic.
I've written virgin sex. I have been true to the pain of it, the nervousness, the insecurity of not knowing what is happening, but knowing something wonderful waits on the other side. Words that help here are calming and romantic ones. Silk. Lace. Satin. Caress. Velvet. Some colors that can work are white, silver, purple, pink. Textures play a big part as well. The word juice gets used a lot, even I am at fault and tend to fall back to that word when I'm at a loss. A writer can try: syrup, honey, nectar, liquid silk, liquid satin. Again it is really the writer's preference to the scene before. In the following example see if you can feel the nervousness and then the eventual promising climax.
