This is a serious topic i am currently investigating, maybe forward on a thesis as to whether the pleasure centre relies more towards the aerobic moton or anaerobic. Society usually has a preconceived noton that anaerobic sexual motion(encouraged by porn) is the most effective form of pleasurable experience but if we look into ancient context , sex is primarly a form of energy exchange that seem to dictate more towards aerobic motion. Thereby, i am forming the hypothesis that distance runners are much better equipped in the transmission of sexual energy, although physically most seem to appear frail. p.s: do not confuse sexual energy wih physical immpact on the partner.
So what are your thoughts?
