I understand that a woman enters janabat when her husband enters her to the point of circumcision. however I wanted to ask if her husband stimulates her with his hands to the point of orgasm, does she enter the state of janabat?
Also are there any other ways and actions that cause a women to enter the state of janabat?

The fluid which a woman discharges in the state of lustfulness and which is called ejaculation – which normally takes place during orgasm – is treated as semen and it will cause janabat (in which case ghusl becomes obligatory). That is to say, ghusl becomes obligatory irrespective of whether there is climax or not. As for the fluid which comes out without lust or the fluid that comes but does not spread out to the underwear and which is only created with little sexual provocation, it does not cause any taklif (obligation) and if there is little fluid that reaches even the underwear but it is little, it is not considered to be ejaculation, so ghusl does not become obligatory.
