Frequently asked questions
What does a penis ring do?
It restricts venous outflow from the shaft. Blood flows in normally but drains out more slowly, so the erectile tissue stays engorged and the erection stays firmer for longer. It does not create an erection — you need to be able to get at least partially hard for it to work on.
How do I find my size?
Measure erect girth at the thickest part of the shaft, divide by 3.14 for diameter, and match it against the sizing chart
. If you are unsure, the three-ring Red Tiger set removes the guesswork for $24.99.
How tight should it be?
Snug with steady pressure, never painful. You should be able to slide a fingertip underneath with mild resistance, and it should not rotate or slide on its own.
How long can I wear a ring?
Thirty minutes maximum, every time, and never while sleeping. Set a timer rather than trusting your sense of time.
What are the warning signs I should remove it?
Numbness, pain, throbbing, coldness, or any dark, dusky or purple colour change. Any of those means remove it immediately and size up next time.
Who should not use a constriction ring?
Speak to a clinician first if you take blood thinners, have a bleeding or clotting disorder, sickle cell disease, Peyronie’s disease, an existing penile injury, or reduced genital sensation. Reduced sensation matters most, because the warning signs above are things you feel.
Do rings help with erectile dysfunction?
For holding an erection you can already achieve, yes — constriction rings are established conservative tools in ED management. For getting an erection in the first place, no. New or worsening ED should be assessed by a doctor, since it is often an early sign of cardiovascular disease.
Can I use a ring with Viagra or Cialis?
There is no interaction — one is mechanical, one is pharmacological. Tell your prescriber what you are using so they have the full picture.
Do rings help you last longer?
The evidence says no. A 2007 study of 42 men with premature ejaculation found constriction rings produced no meaningful change in time to ejaculation. If lasting longer is your goal, a topical and behavioural techniques are the honest answer — see the lasting longer guide
.
Does Mammoth Force sell a vibrating ring?
No. Trigger and Pulse vibrate, but Trigger is finger-worn and Pulse is a wand — neither is a constriction ring.
Is the Titan Trainer a penis pump?
No, it is a sleeve-style performance trainer. There is no vacuum erection device in the current lineup. The penis pump guide
covers what to look for if that is what you need.
How does a delay spray work?
Anaesthetic sprays reduce sensitivity in the glans, raising the ejaculatory threshold — that is the mechanism with trial evidence behind it. Botanical topicals like Fortify are positioned around circulation and comfort instead. Check the label so you know which you have.
Will delay spray numb my partner?
An anaesthetic spray can, if you skip wiping off the excess. Apply, wait the time on the label, wipe off, and use a condom if you want certainty.
What lube should I use with a silicone ring?
Water-based. Silicone lube degrades silicone over repeated contact — the ring goes tacky, then gummy. See silicone lube with silicone toys
.
Is oil-based lube safe with condoms?
No. Oil degrades latex and can cause condom failure. Water-based and silicone-based are both fine with latex.
How do I clean a ring?
Warm water and mild unscented soap after every use, rinse thoroughly, air dry completely. Store dry and away from other silicone items.
When should I replace a ring?
When it develops tackiness, tears, discolouration, or a permanent stretch. A ring that has lost its recoil is not applying even pressure any more.
Is the packaging discreet?
Yes. Plain outer packaging with no product imagery or indication of contents, and a non-descriptive billing descriptor.
Is shipping free?
On US orders over $50. Every bundle clears that, as does almost any two-item order.
What is the return policy?
See the refund policy
for current terms. Hygiene restrictions apply to intimate products, as they do throughout this category.

Erectile dysfunction can be an early sign of cardiovascular disease, diabetes or hormonal problems, so a new or
worsening change is worth a conversation with a doctor. Talk to a clinician before using a constriction ring if you
take blood thinners, have a bleeding disorder, sickle cell disease, Peyronie's disease, or reduced genital sensation.
