Does touching the penis or buttocks during ghusl necessitate wudu after ghusl, given that ghusl from janabah suffices for wudu whether the person in a state of janabah performs wudu before ghusl or not?

If a person in a state of ritual impurity (junub) performs ghusl and touches his penis during the process, the act of touching is categorized as follows:

- Touching with desire: He must perform wudu' after completing ghusl.

- Touching without desire: He is not required to perform wudu'.

As for touching the buttocks, testicles, or surrounding areas, this does not invalidate wudu'. The difference of opinion regarding touching the anus is similar to that concerning touching the penis.
