Ohnut

Four-ring depth-limiting buffer.

Ohnut is a set of stretchy (very stretchy), stackable rings worn around the base of a penetrating partner — whether that be penis, dilator, or toy. It limits insertion depth without limiting sensation. Rings can be added or removed at any time.

Clinical applications

Ohnut may be appropriate for patients experiencing deep or collision dyspareunia related to:

Gynecologic conditions

Endometriosis, adenomyosis, fibroids, PCOS/PMOS, pelvic organ prolapse, IC / painful bladder syndrome, menopause-related tissue changes.

Surgical recovery

Hysterectomy, gender-affirming vaginoplasty, abdominopelvic surgery, cancer treatment.

Functional / musculoskeletal

Pelvic floor dysfunction, postpartum recovery, scar tissue and adhesions.

Neurologic / psychogenic

PTSD, hypertonic pelvic floor secondary to trauma.

By limiting depth, Ohnut may help:

Reduce pressure on tender or inflamed structures
Decrease tension on scar tissue or adhesions
Downregulate the nervous system sufficiently to allow for pelvic floor relaxation

Dyspareunia often has complex underlying causes that require a multidisciplinary team to address. Ohnut allows patients to maintain intimacy while that work is underway.

Three things to tell every patient

1

“Start with 3 or 4 rings, not 1.”

Starting with one ring and needing more can feel like failure. Starting with three or four and taking rings off doesn’t. Start with more rings. We also recommend reinforcing that the rings are not a progression — depth tolerance varies by position, cycle, and day. The number of rings used is not a metric of success.

2

“It feels like going all the way in.”

Reframe partner concerns proactively. Most patients are already worried about being a burden. Get ahead of it: “For your partner, it feels like going all the way in without worrying about going too far.”

3

“It sparks conversation.”

Patients who previously responded to pain with silence, guarding, or shutting down now have language around a neutral object: “Want to add a ring? Take one off? How does this feel?” That verbal shift toward establishing trust and safety is critical.

Vibrating add-on ring

Stacks anywhere on the stack and can be rotated for either partner’s sensation. Vibration is useful for increasing blood flow and oxygen to surrounding muscles, encourages relaxation, and invites exploratory enjoyment for both partners.

Practical notes

HSA / FSA eligible.
Lube is non-negotiable. Water-based or silicone-based — both work with Ohnut’s body-safe polymer blend material (not pure silicone, which isn’t stretchy enough).
Menopause / ED tip: if a partner is concerned about erection loss, suggest they try Ohnut alone first to get used to the feel before bringing it into shared intimacy.
Cleaning: soap and water. Fragrance-free preferred.
