Coagulation of semen

Hello all. I just had a question I've been trying to figure out for some time. I went to a urologist a while ago due to lets say a pain in my testicles that started after getting close to getting off but not getting there. Anyways I considered it to be enough to make an appointment.

So the problem so to speak is that there are, I don't want to say chunks but, globules of semen in my ejaculate. Which are a slight tint of yellow among the white. So when I went to the urologist I asked him about this also. He said that it was probably protein coagulating inside my testicles and that I should masturbate more and possibly change my diet. Have any of you heard of this? He asked me the texture of the globules and they are kind of jelly like. He compared it to tapioca pudding, lol. But it is not like this is all of what all of my ejaculate consists of. They are just in it.

I'm not very concerned as the Dr. didn't make it out to be an extremely bad thing and he said it was more common than I was thinking, I would just like to possibly correct it. I have not tried anything yet but was hoping that maybe a protein shake would fix things up. Any thoughts? Thanks
