what is the bais shmuel (20.5)'s source that relations without an erection forbid a woman from her husband (the bais shmuel sefaria.org/… , tzuras hadaf beta.hebrewbooks.org/tursa.aspx?a=eh_x7592 ) i can not find it, if it is so i need to correct judaism.stackexchange.com/a/67346/5120 (i thought no erection means no relations)

if a wife of a cohen was raped (is she also a zona if there was no erection?)

am i misunderstanding something?

it looks like she does become a zona hebrewbooks.org/rambam.aspx?mfid=100651&rid=4048
