Do satanic whispers (of cursing, slandering, and sexual thoughts) invalidate ghusl or wudu’ if they occur during them? And does the straightening of the penis invalidate ghusl?

"Whispers (waswas) have no effect on the validity of wudu (ablution) or ghusl (definition) (ritual bath). One must turn away from them and pay them no mind to avoid evil. As for penile erection, it does not invalidate wudu or ghusl. What invalidates them is the emission of semen, which necessitates repeating ghusl. If madhy (pre-seminal fluid) is emitted, it nullifies wudu and requires purifying whatever it touched on the body and clothes, then performing wudu."
