The main things to watch for with urine are, smell, does it smell unusual, repeatedly. It's perfectly normal, now and again, to pass strong uring. But it should only be now and again.
Colour. Is it between a little yellow and almost clear? It's perfectly normal to pass something a bit strong or really clear, now and again.
Flow. When it flows, if there is a blockage developing, then you will feel almost like its being held back. That feeling you get when your bladder is saying it's full, you will get that while urinating.
If it isn't uncomfortable then it's OK.
One other thing. If you are on any nutrient suppliment, that will affect the colour and consistance of your urine. Perfectly normal.
Some people take a while to go. Women are generally like this, mainly because it takes them so much longer. They need to find a clean toilet, men can do it against a tree, They need to remove a lot more clothing, they tend to be quite particular about replacing it after.
Consequently, women often hold it in for longer. Their bladders have more in them and they take longer to empty
But you need to be drinking a lot more water. Coffe is OK, but not enough. The easiest way to do this is to get a decent sized glass of water and take it to bed. I always take a 500ml glass of water with me.
Don't try to use your pelvic muscles to force it. No-one should do this, though most of us do, now and again.
