30 yo, no morning woods

Hi, since i would say two years i almost never (probably once a month) have a morning wood. I also noticed during masturbation I quickly loose my erection during the act. To regain it again while focusing on getting hard. I never thought much of it, thinking it was just because i'm not turned on enough. I would also add that i have urniary urgencies since i'm 23. Never done anything about it, as i managed all these years but these last years having a slighty wet underwear when holding up for too long is an occurence.

Any advice? I finaly took action and have apointements to the urologist and for a brain scan.
