What Causes Penis And Testicles Discomfort With Sensitive Glans?

Hi, I've had some general strange things going on in my genital area. I'm a 29 year old male. Not sexually active at the moment. I've had feelings in my penis and testicles that can best be described as discomfort. My sex drive has been basically non-existent. My penis (near the tip)can be extremely sensitive at times, and I've noticed that my semen is very gelatinous. Almost solid. I'm not sure what to make of it. This has been going on for at least two months now.
