BDSM: This is a bit of a catch-all acronym with several meanings, including Bondage/Discipline, Dominance/submission, and Sadism/masochism.

Top: The person who is swinging the flogger, doing the fisting, trying you up or suspending you, or doing all those wonderful consensual things to you. A Top can be a submissive, Dominant, switch – or none of the above.

Bottom: The person receiving the flogging/fisting/bondage, etc. Again this person can be a submissive, Dominant, switch – or none of the above.

Dom/me: “Dom” is a male dominant; “Domme” is a female dominant. Often people who introduce themselves as a Dom/me really mean that they are a top. However in many cases A Dom/me may not always be a top. Dom/me is also used by the Dominant in a power exchange relationship

submissive: As with Dom a submissive can be either a bottom or be their role in the power exchange relationship.  A submissive can also be a top.

“Boy, I need some tie-up time! Bring me my leather strait jacket, strap me in, and do not let me out until morning.”
“Yes, Sir. Will you be wanting your gag?”
“Yes, please.”

Master / Mistress: The person leading the power exchange relationship(s). Master is primarily by males, in some circles females may be called Master.

Slave: The person in a power exchange relationship who is not in charge. This term in non gender specific

TPE: Total Power Exchange. A relationship in which one person is the lead and one is not. (This is a raw definition). The exercise of a TPE may be detailed in a contract with well defined roles.

Total Power Exchange (TPE)

Definition – What does Total Power Exchange (TPE) mean?

Total power exchange (TPE) is a relationship dynamic that occurs in a BDSM relationship where the dominant partner has total power over the submissive in everything. TPE always applies in sexual situations, but generally also refers to the dominant having power over all other elements of the submissive’s life.

TPE is a turn-on for a lot of people because of the level of trust involved. The submissive essentially gives their life away to the dominant. This is also a huge responsibility for the dominant and should not be taken lightly.

Kinkly explains Total Power Exchange (TPE)

TPE can be used in day-to-day activities, or it can be used for just a few hours during play to spice things up.

This type of play is not about micromanaging a person’s life; it’s about a submissive giving complete trust to the dominant partner and believing that he or she will have the submissive’s best interests and pleasure in mind.

What can be so hard to understand is that the submissive actually control. That’s because in sane, respectful D/s relationship the submissive can stop the play at any time. It’s all about the submissive being able to give up control and the dominant being able to exert control in a safe, consensual way.

Power Exchange Relationship: In my view point a PEW – Power Exchange Relationship is just similar to that of a TPE, but the submissive is not giving up complete control of their life or only control in a scene/play. This can be a little broader and it is a part of the D/s and BDSM Kink worlds, Once again it comes down to consent and negotiation.
