True sexual intimacy between a man and a women is indeed a union of body, soul and spirit. My own view of this (and I am NOT judging anyone else!) comes from a Christian perspective, as compared to the Eastern spirituality that underlies tantric sex, etc. I will say that my wife and I and adopted some of the basic concepts of karezza and we are having the best time we have had in decades (without any O on my part). When the goal is not O, the experience can be wonderful. One study says that sex after penetration lasts an average of 5.4 minutes. Karezza techniques can stretch that into hours! I was skeptical of retention. If I can get to 90 days PMO free, on day 91 I may just try sex-with-O again. I have a sneaky suspicion that might be the last time. It sounds crazy, but so far on this reboot I now have more sexual energy than I have had in a very long time. And retention feels great. And sex-without-O feels great. One technical caution: extended lovemaking this way can greatly increase the possibility of a urinary tract infection in the guy. Always pee after sex (I think everybody knows that anyway) and consider a condom with a good fit. You can finally get them in all kinds of sizes!
