Does physical fitness affect ejaculation? -
When I was younger and in better shape I could ejaculate more and shoot farther. Could this be because of physical fitness?
This could be because of physical fitness, but not the muscles you are thinking of. Younger males tend to have more urges, and therefore tend to masturbate and partake in sexual activity much more, working a particular muscle group at the base of the pelvis which is known collectively as the PC Muscles (at least I think that is what they are called). These muscles control the transportation of the semen as well as the contraction of an orgasm, and the constant usage in your earlier years may have built these muscles up. As you age, however your urges decline, and the amount of masturbation and sexual activity you partake in will inevitably decline as well, meaning that the PC Muscles will see a lack of usage, and like any muscle, will atrophy. This may be why it seems that your ejaculation does not seem as prominent as it once was. I certainly hope this helps!
Perhaps it does, but it has been already established that having better physical fitness helps in that general area.
My guess is that physical fitness does affect it.
Hey, the only way to find out for sure is to improve your physical fitness.
Nope. That happened because you got older.
