yes it is sorta raised and myself i think it is a blood vessel but really small one. and it doesnent hurt
Hey, Grant. Don't worry. Sounds to me like everything's normal.
Semen is made of mostly sugars and proteins, very similar to egg whites. Normally it's white to yellowish in color and the same consistency as shampoo. This can vary from time to time though, depending on the temperature, your diet and how "old" the semen is. Sometimes you might notice little clumps in it like jello. That's normal.
The red spot on the tip of your penis could be a vein. Is it raised? Does it hurt? Sometimes you can get a pimple on it, just like anywhere else.
I don't think you have anything to worry about.
