Good morning dear. It could be because of
STD or could be because of other parameters which are making your semen watery. Your doctor needs to understand what all is happening in your body.
Just for the record, it could be a normal issue like wrong concepts. Ex: multiple ejaculations and thinking that every time the semen should be viscous. If it is true then its a wrong assumption.
In anyway, you need to get your case assessed in detail first.
Please check out our website Faqs page and read about level 2 consultation.
