Here is the link to the Urinal Dynamics abstract:
Targets! You can buy a target for the toilet–it works. http://www.urinalfly.com/
Dmd - high five, for great minds think… Mr. B suggested precisely that solution when I read the OP to him. 
Hmmmm…
OP joined CC and posted and hasn’t come back…
If she does, she’ll be shocked to see the conversation she sparked!
And if she doesn’t, then perhaps it wasn’t a real issue after all. But it did create some lively conversation!
I started my boys off young - there was a “cleaning kit” in their bathroom and they were expected to clean up the toilet/floor if they made a mess. I’m not normally a clean-freak, but to me, it is pretty disgusting to walk into a bathroom and have urine splashed all over. I have friends who have said, “well, that is just part of having boys in the house.” It is definitely NOT! I don’t remember really ever having an issue with my boys, and I don’t think they even had to routinely wipe up- they just must aim carefully (I don’t really know but it just never has been a problem). I do know that my boys can’t understand when their friends leave a mess as they have both said it’s not rocket science. The tallest is 6’2", so not as tall as some but still, If he can do it, I think most men could. I would say the OP should make it easy for her son to clean up - put a spray bottle with cleaner and sponges under the sink- and then tell him to clean up after himself. He should learn now before it is time to move off to college- roommates may not be as understanding as Mom if they walk into a puddle of urine in the middle of the night.
^Not to mention a girlfriend. I think all of us moms of boys owe it to their future girlfriends and/or spouses to make sure our sons know how to handle this issue and also how much it bugs the women in their lives! 
I have 3 brothers and 2 sisters. We all shared a community bathroom, and was definitely NOT part of life in our house either.
I have two sons and a daughter and they were taught to clean up after themselves from an early age. Youngest son is 6’3" and is visiting me right now, and he even puts the seat down after himself! Seriously, installing a higher toilet is a nice idea, but fact is that most places use standard size everything and no one is going to want to clean up after a guy who pees on the floor! Time to give your son a good talking to and a bucket of cleaning supplies…
Interesting that the OP hasn’t been on this forum since posting this question. Maybe she is cleaning up,the mess.
Hahahaha, great one Thumper1!
@dmd77 - The men’s rooms at Happydad’s workplace all have those flies in the urinals. The former director had seen them in use elsewhere and ordered the stickers for the whole facility. All reports indicate that they are effective.
I also have a 6’6"er. A taller toilet helps. If we would have had room, I would have put in a urinal. The only thing that made it tolerable was to clean his bathroom twice a week.
I never understood why women can’t learn to check to make sure the seat is down before sitting on it. I’d think if the alternative was falling in, a pre-sit check would become second nature. Even if one is half asleep.
I just recently read an article that claims it is healthier and more sanitary to not make your bed. Apparently making the bed traps heat and moisture under the covers, which makes it a perfect breeding ground for dust mites. Unmade beds dry out (we sweat a lot when we sleep) and the dust mites dry out and die.
I will explain it to you: I do not want to grasp and feel in the dark for an upright toilet seat that most likely has old and new / dried and fresh pee splatters on it. Why should I have to touch your pee germs? You are the one who splatters pee when you urinate so you should touch your own icky urine and put the seat back down for me.
^ If the seat is up for the man, there won’t be spatters on the seat. Plus, urine is sterile, there are no pee germs. 
Helloo - pee splatters onto the underside which is the exposed side while you are peeing.
But if you insist on not putting it down, I can just nudge it in the middle of the night so it slams down and wakes you up.

Urine is not sterile, even before it comes out of you and gets contaminated by your skin. Bacteria are present at low levels in the urine of healthy people not suffering from a urinary tract infection, Evann Hilt of Loyola University of Chicago reported May 18 at a conference of the American Society for Microbiology.May 22, 2014
@notrichenough- because a toilet with the lid and seat up look tacky. Your home is not a public restroom. Lids are put on toilets for a reason. The insides of toilets are not always spot clean, even if you clean them frequently. Besides possible visible “residue”, they harbor bacteria from several sources. There are many studies proving that splatter from your toilet when it is flushed reaches up to 6’ or more- so if you flush with the lid up, there’s a good chance your toothbrush or other items on the counter are getting sprayed. Yuck.
That’s your opinion.
We’re not talking about the lid though, just the seat.
If having the seat up at 3AM is too much to handle, I would think having the lid down at 3AM would be equally difficult to manage.
