I Have Been Always Looking For An Answer To The

I have been always looking for an answer to the weakness in my legs and lack of memory after I masturbate. I also have more quick ejaculations and less ability to re-masturbate after doing it once -less sexual will. The will to have sex have weakened as I feel no more as much attracted to, for example, a partially naked woman body (bikini) as I used to be when I was 18 and 19...
Only after two or three squat sessions at the gym that I regain my leg strength. And only after a long time
do I regain my memory and concerntration "function" especially when I eat a lot of varied food.
I think I overused myself and I am so worried to sickness about my future as I would like to marry and have children: I am worried about my wife's satisfaction. I am now more worried about the psychological stress I have because of this issue than about the issue itself. But actually both problems are significantly present in my daily life.

Thank you infinitely for the help you are offering.
