Hello, recently ive realised that when i ejaculate, i produce liquid semen first but then a string-like pieces of semen come out which are not liquidy.

Im a bit over weight, not obeise tho, also i have no pain in my testicles or anything. Its just that normal semen is produced then this type more solid sperm somes out.

Is this normal? Along with the normal abnormalities, will this go when/if i lose weight?
