As the title implies this little article is intended for guys who wish to write lesbian themed sex scenes that appeal to women. While I claim no more expertise at it than other writers, I have been asked by a few people to look at their submissions in the category and one of these prevailed upon me to write this little piece. Thanks Rumple.
The first thing that strikes me when I read most submissions by male authors in the category or as a scene in a different category is the lack of emotive response the scene produces.
The next thing I notice is a hurried feel to the work, as if the author is in a race to get to some goal.
The final major thing is a lack of preparation.
So here are a few suggestions for guys who wish to include lesbian scenes in their works, but feel daunted by the prospect. Keep in mind, the suggestions here are based around broad generalizations. If you wish to include a lesbian scene in a work where it isn't the central theme, such as a BDSM or N/C story, then your overall theme may very well supercede the suggestions.
LACK OF EMOTIVE RESPONSE: Women do read erotica for the simple expedient of getting off, but tend to look for something a little deeper. There is an emotional component to the sex act for women, which seems to be much stronger than most men experience. If you wish to write a good lesbian scene you need to tap into that emotion. Does this mean you need to write a novel or give a complete psychoanalysis of each character to get the response you want? No. What it does mean is you need more than "I loved licking her pussy" in the way of emotion.
What is your protagonist feeling emotionally? Why? What is it about this particular woman that makes her attractive and desirable above others? You don't have to delve into romance novels or use flowery language, but you do need to convey a depth of feeling from your characters that goes beyond simple physical attraction. They don't necessarily have to be in love.
Many emotions can drive people into one another's arms. Friendship, sympathy, fear, even dislike can be the motivators. The point is you need to get those motivators across to the reader.
The most vividly rendered and technically correct description of one woman giving another head, without letting your reader know the why and the feelings behind it will pale in comparison to a relatively clumsy and technically flawed description of the same act where the reader can feel the emotion.
It may cost you a few brevity points, but taking the space to let your readers know what your characters are feeling, beyond the physical sensations, will go a long way to making it a good scene. Building an emotional connection between your character and the reader is one of the most fundamental things you can do to improve upon your work. With a female audience it is even more critical. Most of the F/F erotica I have read by men is emotionally gelded. It may work well for a male audience, but it often leaves women cold.
