I'm having excessive nocturnal emissions since months and also thin and clear. i'm really stressed its not normal.what should i do to check ifim ok?

Likely normal: There can be great variability in the frequency of nocturnal emissions which can be related to age and sexual activity. It's usually not felt to be related to concerning physical problems. Consider seeing a urologist for further input.

Don't worry.: You are a young healthy guy but sometimes that takes the form of what you have described. If you ejaculate during sex but before the woman does or if you can't hold back that can be a problem. You need to find a good physician that you can talk to and work on dealing with it.
