Pegging is using a strap-on dildo for intercourse. Can be used by men (on top of a cage, for example, as a means of denial) or by women on each other, or by a woman on a man for anal penetration.

Keephimlocked refers to the need or desire of a dominatrix to keep her sub male locked in a chastity device.

Hulking is having sex with the man wearing a penis sleeve. Can be used in vanilla sex for fun and experimentation, or bdsm as an alternative to caging.
