Very interesting post and I would like to say that there are several areas that I have done in life where I "Get turned on like sex." The religious and the intellectual or just accomplishing something that is difficult, like successfully changing out or repairing a transmission. And, I hope you are right because I am getting older and that means...LOL. But yes, learning something that I sought after, succeeding at something has given me the tingles like an orgasm it was so pleasurable.
Faith healing successfully was absolutely wonderful.
Thanks @jeff-kubitz, I love what you say here...this is exactly what I'm talking about! Glad to hear your experiences.
