The Church and condoms

Humanae Vitae is pretty clear:condoms cannot be used in the marriage act.Now if a person is absolutely intent in behaving in a promiscuous manner,he may consider the use of a condom.But,and I think this is the point of note,it is not up to the Church to issue pastoral guidelines to people who wish to behave in a promiscuous fashion.The Church has one purpose-to save souls.
