Strap-on training is an activity enjoyed in some BDSM relationships where a submissive interacts with a strap-on dildo worn by a dominant woman. The strap-on harness holds interchangeable dildos which are available in a range of sizes. This allows the submissive to progress from small dildos to larger ones over the course of their training.
The submissive may be "trained" for various sex acts with this strap-on set-up. Commonly, the submissive may be trained to provide oral sex on a phallus (or, specifically, for the act of deep throating), or they may be trained for vaginal or anal sex with the strap-on dildo.
While not as common, some couples may use strap-on training for handjobs as well. If the strap-on wearer has a clitoris, the friction from the base of the strap-on dildo may be orgasmic for them when the dildo is "stroked" to intentionally cause this friction.
Strap-on training may also be known as strap-on servitude.
More About Strap-on Training
During strap-on training, a submissive will interact with the strap-on worn by the dominant partner as the dominant demands. Strap-on training is often a component of forced feminization, slave training, and humiliation.
Strap-on training can also be an effective way to make a slave more submissive and increase their devotion to their dominant partner.
Some kinky couples also use strap-on training as an "excuse" for practical purposes. Having a regular, planned schedule for oral or anal training can gradually make the "trained" partner better at the activity, making future sexual encounters more pleasurable or possible down the line.
This is especially common for purposes of anal penetration. The dominant woman may select a large, currently-unachievable dildo to be pushed inside the receiving partner at a future date. Up until that date, the couple may plan for regular "strap-on training sessions" with gradually-expanding dildos to make safe, effective anal stretching feel like a kinky power exchange activity.
For safety and comfort, every dildo used should be well lubricated during strap-on training. When anal play or penetration is a component of slave training, the submissive’s anus should also be well lubricated.
During anal sex with a strap-on on a prostate-owning person, the prostate gland is often stimulated. This can cause prostate milking and increase the intensity of the orgasm.
