A:
The excretion of thick, sticky fluid after urination without desire is not Maniy (sperm released upon orgasm), rather it is Wady (a thick white secretion discharged by some men after urination). This does not nullify the fast and does not require Ghusl. However, it is obligatory to wash your penis and then perform Wudu'. As long as you did not break your fast and did not intend this before Maghrib, then your fast is valid and there is nothing (else) upon you.May Allah grant us success. May Allah send blessings and peace upon our Prophet Muhammad and his family and Companions!
