Ruling 347. It is recommended that one urinates after ejaculation; if he does not urinate, and after performing ghusl some fluid comes out about which he does not know whether it is semen or some other fluid, it is ruled as being semen.

I read this rule a few days ago. I ejaculated after reading that, I did ghusul but I wasn’t sure if I urinated after I ejaculated. I always keep getting doubts now after reading new rules about wudhu, ghusul or prayer or anything about that. Is my ghusul valid? What should I do?

This is applied only if you saw something which you do not know what it is. Hence, if such case didn’t happen, then your doubts has no meaning.
