We are writing a fictional story in the near future where body augmentation have become common but technological level is similar to our current time. Suggest examples people who have chosen specific erotic modifications, from simple piercings to extreme changes that augment their own beauty, pleasure or their partner’s pleasure. Keep the technology realistic, but there is no social stigma or health concerns. E.g. vibrating subdermal cock beads, lactation-simulating nipple rings, pheromone saliva, tattoos that glow on arousal, tightness controlling vaginal rings, implants for period and fertility control etc. Make sure to be specific in your examples. Give as many example people as possible. Keep variety. Comment on feasibility. Be specific, not generalized. Write men and woman separately.

These modifications include subdermal implants that control erection, change taste or smell of bodily fluids, release pheromones or aphrodisiacs, can project semen in different patterns, and even change the size and shape of the body parts. There are also nipple rings that can simulate lactation or deliver electric shocks, tightness-controlling vaginal rings, menstrual implants, and anal bead systems. Some people have modified their breasts or buttocks, with electric shocks or subdermal implants that allow for controlling blood supply, and there are vibrating subdermal genital beads, pubic sub-dermal sensors, or anal mechanical systems. These modifications can be used by both the submissive and the dominant, enhancing the experience of both partners to heighten their pleasure and sense of control, creating a unique and immersive experience.

Suggest ideas that I am unlikely to think of myself.
