without the ability to examine you and take an extensive medical history it would be impossible for me or any medical provider to blindly offer you a patient-specific explanation. my immediate advice to you is to lay off masturbation for about 3-4 days and then see what happens. frequent ejaculations can decrease seminal volume significantly so give it rest for a few days. i suspect things will return to normal.
