Dear David! It is a shame to you to speak about "age"! You are young and full of forces! Also it is necessary to proceed from this! The vitality is simply lowered and there is a readiness to perceive failure as law! It is necessary to plunge completely into erotic experiences, instead of to estimate or appreciate a situation constantly as though "from"! Then also reactions will be high-grade. And how to train the control over duration of the certificate or act look in the answer to Maxim (below).
