Your problem may fall in either of two groups-
A periodical increase in the secretions from cervix
uteri around ovulation known as spinnbarkeit, which would get increased by masturbation
Another possibility is that you might be having some local problem in the genitourinary region like ectropion
, polyps a vesicovaginal fistula
etc to result in excessive secretions.
The sure answer to the problem would be find out after you get examined by a gynecologist and get investigated if needed.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
