What happens if you get a bit too happy in a massage? I suggest not to worry about it too much. Massage therapist are normally used to it occasionally appearing in endings. When muscles are stimulated, relaxed, and are receiving pleasurable sensation, then a person can become excited/happy in the ending or even during the middle of the session. It is quite common, so don’t try to avoid it and just try to enjoy and relax with the massage. The therapist will respect your boundaries the same way they will expect you to respect hers. Just remember there is nothing wrong with feeling nurtured and euphoric in your body. Maybe pamper yourself to getting a happy massage that is sensual and pleasurable so that you embrace your happy feelings. 

I am based in Victoria BC if you want to find a therapist that won’t be too shy about your happy experience and ending.
