What is the reason for the sudden penile erection that occurs when speaking with friends and acquaintances, and is it a normal phenomenon?

Sodomy has stages: finding pleasure in looking at men, or listening to their voices, or shaking hands with them, and touching their bodies, all fall under sodomy. The second stage is foreplay, familiarity, and embracing. The third stage is committing the major obscenity. Refraining from mingling with men at celebrations, trips, and the like is correct. Prayer should be performed in the mosque if possible; otherwise, it should be performed in any place where a Muslim can avoid falling into what is forbidden, because abandoning the forbidden takes precedence over performing an obligation. It is also recommended for those who are able to marry, as it is more conducive to lowering the gaze and protecting one's private parts.
