I've been having trouble getting an erection and my penis seems a lot softer than it usually is. I can't get fully aroused and I go soft and limp really quickly, and have problems trying to get aroused again. I do masturbate every other day or some weeks 3 times but this has just happened within the past three days, and haven't had a problem like this. Should I go see my doctor about my issue, or is there something I can do.
