Confused, I dont know whats happening after masterbating

I've had two urinary tract infections in my life. Both were from sex. Sometimes the vaginal fluids can move into your urethra and up the urinary tract from the rubbing. If this happens, the fluids will grow bacteria and cause an infection. This infection can move up into the bladder. Worst case, it can then travel into your kidneys and become life threatening. You don't have to worry about that happening to you without you knowing about it though. It is not a silent killer so you will definitely see warnings. You would be in such excruciating pain before that would happen to you. Hopefully you have enough sense to go to the hospital if it becomes that intolerable. While VERY uncomfortable, there isn't need to be scared of having a UTI. It is treated very easily with antibiotics. If these symptoms have been going on for months for you already though, then I'm not sure if you have a UTI. Both my infections only took a day or two from when the symptoms first presented themselves till when I was in a ton of pain and discomfort. If it has a smell though then its probably some form of infection somewhere and should be looked at by a doctor very soon. They will have you produce a pee sample (in a cup) and they will test for an infection that way. It's extremely easy to treat too so no worries there. Just a few days worth of antibiotics.
Drinking lots of water HELPS flush the bladder out to remove more bacteria. However, if there is already an infection, they cannot be flushed out as quickly as they are multiplying in your bladder, and water will not CURE a UTI. Cranberry juice has the same effect. It is also very acidic which will create a high pH environment in your bladder. Many types of bacteria cannot survive in a high pH environment (just like how a jar of pickles can stay opened in the fridge without spoiling for a very long time, it has a high pH). Again though, this will not CURE a UTI. Usually once you have a UTI, the bacteria have grown so out of control that the only thing that will cure it is antibiotics.
Some people are more prone to urinary tract infections. To prevent them from happening before they happen, that is when it is helpful to drink lots of water and cranberry juice. Also, after you have sex or masturbate, go pee. This will flush out any fluids that might have been pushed up the urinary tract before it can turn into a UTI. This is what is working for me now to prevent them.
You really should go see a doctor though whenever you think there is chance of any sort of infection in your body. But don't be worried! If you're not in a lot of pain and your energy is normal then its not an emergancy. I'm worried if you leave it longer though, it will become very painful and discomforting you will be wishing you had gone to the doctor sooner. All the best to you!!! :)
Rule of thumb: If it doesn't seem normal/right, get it checked. Especially when there is an odor.

Ok Thnkxz. this kind of eased my mind. xP

Iv been still drinking water and everything, so the odor is not that strong compared to the times when i dont drink water.

i just dont want my mom to know about it. Like if i get an infection er anything, i dont want her to kno "Oh she masterbates" n shiz like that. Its ackward, for me at least.

But thanks again.
