Ejaculation at night-daily nocturnal emissions, should i be concerned?

This is fine: If you don't have a partner and aren't enjoying your body to the point of orgasm when you're by yourself, this is going to happen. It confirms that you're a normal man. Enjoy your sexuality in whatever way seems right and is responsible.

Nocturnal Emission: Nope. You should not be concerned in any way. This is nature and natural and common. The prostate gland's mission is to keep fresh fluid available to keep sperm fresh and alive. If you are not emptying your prostate gland through regular ejaculation then you will be having these normal night time seminal emissions.
