My after session reaction is entirely dependent on the type of the session and the level of "chemistry" I had with the Domme during the session.

If the session is 3 hours of longer and is a physically demanding session, heavy bondage with corporal play, then I am typically just worn out physically. It's a great feeling, sort of how I feel after an intense workout in gym. If it's bondage with T&D play, some anal or medical play, then I am in that gooey emotional subspace that Mistress Ayn describes in her post on this thread.

On those rare occasions when the chemistry is non-existent, or negative, then it doesn't matter what activities happen in the session. It's just a disappointment for me and my reaction is one of regret and questioning myself as to why I enjoy BDSM.

Fortunately that feeling doesn't last long, I've just had too many great sessions with fantastic Dommes to think back on and that shakes me out of the doldrums pretty quick.
