Salam alaikum Sometimes me and my husband do not do sexual intercourse but during foreplay his semen(cum,thick white fluid) falls on my body. So is gusl obligatory for me? If yes then which gusl. Please reply Regards.
No you do not become Junub if there was no penetration, hence no Ghusl. Semen however is Najis and you need to purify the part(s) of the body it fell on.
