During sexual activity, some women experience an expelling of fluid at orgasm. It may be urine or paraurethral glands fluid. In a woman, paraurethral glands come together in a cluster at the outside opening of a woman’s urethra  and produce a clear or whitish fluid. This may also serve to moisten both the urethra and the tissue surrounding the vagina . The tissue surrounding the paraurethral glands is connected to the vagina and clitoris , and these glands can be stimulated through the vagina. Some people believe this is the controversial G-spot, or the erotic zone that’s said to yield greater arousal and stronger orgasms.
