Biology question - resistance times - variable

[Matty77]

Hello again,

I've posted a little bit about the various 'resistance' games I play on my own at times and I had a biology question to see if anyone might be able to answer this for me.

Most physical activities in life - such as running on a treadmill - you can be sure that if you could run 5km one day, you'll probably be able to run 5km the next day (or further).

But with the resistance games I play I find it impossible to predict whether I'm going to last 10 minutes without touching myself or 90 minutes without touching myself.

Why is that?

It's not the actual masturbation part that I cannot predict - that's fairly standard - once touching starts, within a minute to 3 minutes there's a climax. It's the 'do not touch' time that is impossible for me to predict.

I know it's not dependent upon the type of video I see (or audio) either.

So yeah - why biologically can I sit watching erotica for over an hour without touching one day, and then the next I'm gone in the first few minutes?

I'd say it's because of psychological reasons? Whether you can run 5k or not is mostly a matter of stamina and muscle strength and that doesn't change much from one day to another.
How long you can play the resistance games probably depends on what mood you're in? Even if you don't have massive mood swings, you probably don't feel exactly the same every day, i.e. one day you're impatient and want to relief some tension quickly because you're stressed or annoyed, another day you enjoy taking more time.
