Oh and when my boyfriend and i are fooling around it usually starts to smell a little during that time also.
It's likely you're just one of those women with copious discharge. The fact that you've always had it and that the odor is not too objectionable means it's probably normal for you. Likewise when you're aroused, getting exceptionally wet just means you are a good producer. Since you have already learned to live with it my recommendation would be to continue as you have.
