Some times when i wake up in the morning, i find some wet coming out. Please don't take it as a wet dream, or urine, becuase the sticky stuff comes out usually just after i have woken up in the morning. Most of the days i have to wash my under wear just becasue of that, and sometimes i wash my pants too.
I read it somewhere that if its not semen, just that sticky stuff than we don't need to perform ghusl, and only wuzu is enough to offer prayers. If it is then what about the clothes?. The same stuff comes out during some salacious situations also, though i try to stay away from all that kind of stuff.
