Peace be upon you. According to Grand Ayatollah Sayyid Khamenei (may Allah protect him): If a woman reaches climax and experiences moisture at that moment, she has attained janabah (major ritual impurity) and must perform ghusl. However, if she doubts whether she has reached that state or whether the moisture occurred at that time, then there is no obligation on her.

According to Grand Ayatollah Sayyid Sistani (may Allah protect him): The fluid that exits from a woman's vagina due to desire, if it is substantial enough to stain her underwear, is considered akin to semen (i.e., it is impure and necessitates ghusl). This applies even if she has not reached climax, as a precaution. However, if the fluid exits without desire or is a localized wetness that does not exceed the vagina and occurs due to light sexual arousal, it does not necessitate janabah and is considered pure. If there is doubt about the fluid's exit or its extent, purification is not required, nor does it invalidate ghusl or wudu (ablution), and there is no need to investigate in cases of doubt. The presence of the fluid on some clothing does not constitute a valid discharge if it is light moisture. Source: [Official Website](
