Have been struggling with maintaining my erections for a while now.

I’ve noticed that when I have an empty bladder - I struggle with either getting or maintaining an erection. Similar to when I have morning wood and go flaccid after good long morning piss.

This got me to thinking…. and then experimenting.

When I know I am going to get it up for either receiving oral or topping, what I do is drink water (I could drink over liquids but I like just plain water) and when I have semi-full bladder - I get the same feelings as I do in the morning. With a somewhat full bladder, I can easily get and maintaining my erection.

Am I just making this up? Has anyone tried or heard of this method?
