I'm 23 and i masturbated 1-2 times per day. Just few days ago i've noticed there is trace of blood in my semen. The following day, i tried to ejaculate but it takes much more effort than usual and my erection is weak compared to last time. And i find it hard to be aroused like no sex drive at all. Is it because of a rupture blood vessel. This has never happened before. Should i wait for a few weeks to let it recover or go to a hospital for consultation..
