Chastity contract

Chastity contracts also typically lay out an expectation of how the user should serve the sexual requirements of the keyholder. This can range from direct in-person sexual gratification to the inclusion of phone sex, remote-use sex toys or the provision of explicit photos/videos of the user as desired by the keyholder.

A contract may also include stipulations which control the user’s masturbation and/or porn habits to assure sexual fidelity. Any fitness or health goals can also be managed effectively from a distance as well as between cohabiting partners.
Chastity with a professional

Although chastity is a form of bondage well-suited to relationships with a D/s dynamic, many people who are unpartnered still enjoy power play and surrendering their sexual agency.

You will no doubt be aware of the stereotype of the high-powered businessman who seeks out the professional dominatrix in their private time to enjoy a respite from the burden of responsibility and control. However, in my 10+ years of experience as a pro-domme, I've encountered people of every gender from all walks of life. There is absolutely no shame in engaging a professional to indulge your kinks and fantasies.

When engaging in chastity with a professional keyholder the relationship dynamic is different to that within a partnered couple. The purpose of the arrangement in this case is to cater to the user’s requirements/requests which may be geared toward self-improvement (e.g. pornography addiction, health goals or motivation) or to fulfil a fetish and is almost always based on a financial agreement.

Just as you would pay a plumber or personal trainer, a professional keyholder is unlikely to engage with clients on an unpaid basis, unless in rare circumstances such as the user offering an exchange of professional services.
Vetting & red flags

Giving complete control of your genitals to another person is a very serious responsibility and it’s important that you do your research before handing over any keys! Whether you are choosing to engage in chastity with a partner or professional, safety and the user’s health should be your top priority.
