Sex, isn't it grand? Especially considering the amazing wide variety of persons, places and things there are out there to fuel our sexual appetites. Considering the many odd fetishes and sexual practices that people indulge in or fantasize about, erotic writers have a rich fertile place to look for story ideas.
Of course this rich fertile place for story ideas is also a rich fertile place to find sexual gratification. Within the bounds of common sense and the specifics of your locality's laws, all that is holding you back is within yourself. Even though you may not dare to try some of the things I describe they are often interesting to think about.
Guys, imagine yourself kneeling in front of a beautiful tall woman, or women imagine a man kneeling in front of you. Imagine the guy moving forward and slipping his hard cock between your knees for a fast and hard knee-fuck. Well that is
Genuphallation
or rubbing the penis between a partner's knees. This certainly adds a little color to the phrase, "Knee high to a..." or perhaps not.
For those of us writing for the Mature category we often write about
Gerentophilia
or the attraction of some people to significantly older partners. Some people are aroused in some way hoping to reconcile the lack of affection they may have experienced from a parent or others may just prefer the compassion, intelligence and experience of older people. There are also rapists who only attack older women. This is also called anoraptus.
The transsexual and cross-dresser category is often home to stories of
Gynemimetophilia
or those aroused by a male impersonating a female or male to female transsexuals. While this is only half the transsexual equation I imagine there must also be a term for those turned on by women impersonating a man or female to male transsexuals.
When writing either S/M stories or gay stories consider the
Handkerchief Codes
where a person indicates his or her preferred sexual activities based upon the color of a handkerchief and where it is worn on the body. Some gay and S/M groups use handkerchiefs to signal potential partners of their preferences. Generally if a handkerchief is worn on the left side, it means the wearer is a top, while if it is worn on the right side, it means the wearer is a bottom.
The color coding offers a wide variety of sexual activities to advertise:
Black ------------ Heavy S/M
