welcome to HealthcareMagic
You have problem of intermittent urine flow and frequent urination
.From what you described I guess there can be one of the two problems you have:-
-either you have got enlarged prostate
which is a rare thing at your age of 24 yrs
-secondly you may have developed a stricture in urethra
or have problem with the sphincter of bladder.
For this problem I would suggest you to consult a Urologist
for opinion.He will examine you;if required investigate you further and advise the treatment accordingly.Do not worry consult a Uroogist he will help you to solve your problem.
