Why do men leave the toilet seat up?

Be happy we do pick the toilet seat up. Would you rather us leave it down so you females be disgusted to find yourself sitting on a toilet seat full oft wet piss? LOL

It go's both ways, men pick it up, women put it down. 50/50 put in your part. So the real one's who are lazy are the ones that are complaining about men not putting the seat down.

Why do women leave the toilet seat down?

In Japan you can use toilets where the seat lifts automatically when you enter the bathroom. The US has some catching up to do.

toilets are made with NO seat that is natural, adding a seat is a extra & not how a toilet should be so we leave the seat up so the toilet looks natural

& it stops us pissing on the seat SO THANK US dont complain

That will forever be a conundrum (sorry for men, that means a confusing or difficult question).

But a much more general problem (which includes this) is WHY DON'T BOYS AND MEN HAVE ANY MANNERS?

We need it up. You need it down. Men invented toilet seats for your benefit. Stop complaining and be grateful you've got one.

I don't. I always leave the toilet seat closed. Oh dear, perhaps that is less than masculine of me...

Because they don't sit when they pee and it's just too easy to leave it up and exit the bathroom. I'm married and my husband does it all the time, this is his excuse as to why. Good luck

I just piss on the seat....I don't flush either, out of spite

Well we obviously we pee like that but some guys are lazy and dont put it back down let alone flush
