It's true that many men will develop these types of symptoms later in life due to something called BPH (benign prostatic hyperplasia), which is essentially when the prostate grows too large and starts "pinching" the urethra closed, which subsequently may lead to symptoms such as difficulty starting a stream or completely emptying when they go. However, your 30's is way too early for this to begin occurring. I would start with going to your PCP first so they can do a physical exam and ask more questions, and then they can help decide whether or not a urology consult is appropriate for you.
Piggybacking... had this start happing to an extent sometime in my 30s or 40s, and figured this was just attributable to aging... Would a urologist visit typically be warranted if there's no other symptoms or related trauma that could have caused it?
