Excessive Vaginal Secretion. HELP!

I dont know any other way to say this, so I am sorry for the vulgarity....
When I have sex, I have TOO MUCH vaginal secretion. There is no smell, and it is more watery type liquid (and its not urine).
I've never had a problem with the wetness in past relationships. Its excessively wet to the point that he doesn't feel the "tight" sensation (or more friction than he could normally feel) and it doesn't fully arouse him anymore...The extra wetness has been more than the usual lately, and now I'm feeling less pleasure as well.
I'm beginning to worry there is some abnormality going on with me. Possibly an STD? I'm so scared. 
Does anyone know what could cause this??? HELP!
Is there something to reduce the wetness? I don't know what to do.

No need to be embarrased.  Shall i  say welcome to the club. DITTO for me but not as much... Question: how Often or not do you have sex? I might have a sort of solution or help for you. Depends on your honest answer. ok

Well it is very common and do not worry so much, ideally u must seek medical advice on this topic to help you get better picture.
