I am doing some writing after a rather lengthy pause and discovered that I feel... bored when writing sex. The mechanical part - poses, A going into B, orgasm descriptions, tempo and angles. It does not feel like a creative, exciting activity but like a monotonous task. It feels like I am adding nothing new and merely rehashing and rewriting scenes I have already written in one way or another. I still like writing erotica. I like writing a story. I like building up to sex. I like the aftermath scenes. But when it reaches the point of writing a sex scene, it feels like "here we go again" not like something I enjoy doing. Have you experienced this? Have you fixed it in some way? Perhaps it was just a phase that went away?
I'm still at the stage where I don't even feel confident writing sex scenes in the first place, but I can already see how it could be difficult to keep coming up with fresh ways to put them together. And at a certain point, if you try too hard to write something new and original, you could easily go too far and just make something weird that takes the reader out of the action. Is part of the trick that, even in an erotic story, not every sex scene has to be written in detail? I can certainly imagine situations where I'd leave the physical parts mostly up to the reader's imagination and focus on (as you say) the buildup, the scenario, the relationship, how the characters feel about what happened. The detailed stuff would feel a bit more special if used sparingly sometimes.
