You may be more healthy than me. I just came once with Lynn and the poor woman had to do a lot of work. No problems with erection, I just had a hard time getting to the finish line. But I loved every minute of it. Three factors in play. My body varies, despite all the supplements I take. I seem to have a cycle that lasts about six weeks (some weeks I do not cum much, and other weeks I cum twice or more per day and am more sensitive). I do not know if that is a real cycle or a consequence of different lifestyle factors (sleep, diet, exercise, stress, etc.). Once I develop chemistry with a woman, usually over three or more sessions, the number of times I cum with her can go up quite a bit (e.g. five times each with a couple of favorites over the summer). For me personal connection is a greater factor than attraction. And they get to know me, my likes, dislikes and timing. And lastly, my MSOG events usually involve THC and a little wine. I have to drive to E-Spa, so I cannot be inebriated. Also, I am taking a month off from THC and alcohol to reset - the dose of THC edibles I need to get high has become ridiculous. I overdid it (again) with porn so I am just sticking with cam girls this month. My Sober October.
