There are two positions we enjoy that rarely turn up in porn, so we think they are under-rated, and many couples may not have ever thought of them. They are mainly about masturbation, not penetration.
The first is me and my OH lying flat on our backs, with our heads at opposite ends of the bed, our genitals touching and our legs bent, so our feet are flat on the bed (got the picture?). It’s great for mutual masturbation, handjobs, etc, and if you are feeling flexible, you can manage some vaginal or anal penetration.
In the second position, we are both sitting up straight, my OH with her back to the headboard and me in front. I masturbate while she licks, sucks or bites my shoulder, neck, ears, etc. Sometimes I can get her to spit on the side of my face too, although she’s not often up for that. You can also swap positions, with similar effect.
These positions might sound quite tame, but they can be feel really intimate and hot.
