Question: Assalamu alaykum,
Do I need to perform a ritual bath after wetting my bed with urine during my sleep?
How can I know if sperm has also exited?
No, you do not have to perform a ritual bath (ghusl) after wetting the bed. However, you do need to wash that area of your body so that it becomes purified again.
As for the exiting of sexual fluids, this would necessitate a bath if certain conditions are met. Please see: Wet Dreams and Ritual Purity: A Reader
And Allah Most High alone knows best.
