Urinary difficulty after ejaculating

[odessy]

I am 19 years old and after masturbating/intercourse i get the urge to go to the bathroom immediately afterwards, however it is not the same feeling as i get when i normally need to urinate, slightly more uncomfortable. When it is harder to pee than usual, i need to force it out and it comes out at a high velocity bot not a large volume (as if the radius of the tube has been decreased so the flow rate has to be increase to release the same volume as when i regularly urinate.) It is an uncomfortable feeling when i am doing this and i quite often spend a long time on the toilet  as it feels though i can not completely empty my bladder and that when i think i am finished a small amount may leak out and i quite often need to cotinue going to the bathroom frequently. When i am urinating and after wards there is a slight pain/uncomfartable feeling that seems to inside my penis, feeling like it is coming from the tube in which my urine flows. This as only occured once or twice having not recently ejaculated. I was mainly looking for some suggestions of what could be occuring and wether this is something that may put my health at risk if i don't get it checked up by a doctor. Thank you

Thank you for your question. This is not related at all to the specifics of this forum, but I will address your questions.

Firstly, I would urge you to practice safer sex practices by utilizing condoms. Secondly, during erections it is difficult to urinate because 1) the urethra becomes constricted and 2) the internal urinary sphincter prevents urine from exiting the bladder during coitus.
Finally, consuming too much protein may have an adverse affect on your kidneys. Diets high in protein can force your kidneys into flushing toxic ketones from your body at an increased rate causing dehydration. Dehydration puts stress on your kidneys and heart.

Sincerely,

Sorry I also forgot to add that I tend to get thirsty quite easily and drink a large amount of water causing me to urinate very frequently. However this only seems to occur when I train alot. I train anywhere from 2 - 8 hours a week doing mixed martial arts. I have a diet very high in protein(150-200g a day and i am also taking creatine monohydrate.
