Yeah, well. I don’t get a woody every time I have to pee.
But, when I have a woody in the morning & I do have to pee, it’s really a stiffy. And it don’t go away until I do pee. YMMV.
Since the OP question was about sex & not reproduction, no one’s brought up anal sex yet?
To hear those that are into it talk about it, it can be pretty darn pleasurable. I always wondered why God/evolution put pleasure sensors “there.”
This peeing through morning wood phenomenon can be a real pain in the ass , if one tries to perform with the downward direction required to maintain cleanliness in the bathroom. I don’t know about the rest of you guys, but I don’t even let my wife see me pee in that condition as I’m quite sure the bent over double position centred over the toilet must be the most ridiculous pose ever presented by a human being.
now i am gonna have to follow my SO to the bathroom in the morning 
Ya know, relieving yourself with morning wood is much easier if you just SIT on the tiolet and lean forward…
Sure, if you’re short and sporting slouching wood at less than horizontal inclination. Any downward manual pressure to direct the anticipated stream into the bowl seems to have the effect of a kink in the hose.
I have tried your method by carefully inserting Herman through the opening of the seat first before settling in your position with the result either shooting the 1/2 inch space between the seat and the bowl rim making a mess of the bathroom floor or suffering the back splash of the extremely short range ricochet.

So is the penis primarily for urination or reproduction?

Thats a thinker…
Nitpick - excrement is waste, crap, shit. At least in biology it is that way.
Dude, my intention is not to make fun of you. I’m pretty sure you have one of those low flow, water conserving whatever-it’s-called toilets.
I’m no John Holmes, but I sit & stick Mr. Happy with a woody between my legs, he’s taking a swim. I’d rather he didn’t, so I’ll do the silly looking “bend awkwardly over the toilet” technique.
Having tried various techniques, I have managed to perfect “the sitter” by sitting WAAAAYYY back on the seat, leaning forward, and tilting Mr. Happy only a couple of degrees downward to avoid “kinkage”.
Sitting that far back on the seat would make a terrible mess if I was to #2 in that position.
It works for me. I just thought I would offer my tip. 
What exactly are you trying to say here? That urine isn’t waste, or that it isn’t excrement? It’s both.
And as a matter of fact, feces mostly isn’t excrement. It’s only excrement if it’s produced by the body as a by-product of some reaction, whereas feces is mostly undigested food.
But if you want a really interesting fact, the body’s primary excretory organs aren’t the kidneys, either. You excrete more waste, by mass, through the lungs than in any other manner.
