text: whats causing this frequent urination condition? hello, i'm a young man in my 20's and i have a frequent urination condition. my prostate is not enlarge and i'm not diabetic. i will urinate both days and night very often. sometimes when i urinate, i have to wait for a few second for the urine to come out and lots of times not a lot urine comes out. further to the frequent urination condition, my erection has weaken. i can have an erection but not for long. thank you for your understanding. you can email me as soon as possible. both of those symptoms indicate a weak pc muscle. this muscle is responsible for both starting and stopping the flow of urine as well as erection strength and holding power.  fortunately, performing pc exercises (also called kegel exercises) will improve your pc muscles greatly.  as for the issue of over urination, see a doctor as this may be a separate health issue.
