Male 64 with partner not completely interesting of the karezza path, so she finishes with an orgasm. However I have been living the karezza/tantric way for 12 years, but lately I have sometimes noticed weaker erections and a little less desire. Ejaculations are not interesting longer, but to stay close to the limit for long time is what I enjoy. I'm have been much more energetic and creative and filled with love feelings since I avoid ejaculations. However I have found out that there is some kind of taxation to stay close to the limit for an hour or two.
