Does a woman's reaching climax through her husband's foreplay without intercourse necessitate ghusl, given that she cannot distinguish between female discharges?

The woman's maniy is thin and yellow, and it is characterized by two signs: its smell resembles that of a date palm spathe or dough, and its emission is accompanied by desire, followed by relaxation. A woman reaching orgasm without intercourse does not necessitate ghusl unless maniy is emitted. If she is doubtful about what has been emitted, she may consider it maniy and perform ghusl, or madhiy and wash the affected area and perform wudu'.
