Just as random information, I was curious so went hunting, and so far this is what I can find from the Vatican on the limits of sexual practices (stress mine):

Quote:

9. This love is above all fully human, a compound of sense and spirit. [...] It is a love which is total—that very special form of personal friendship in which husband and wife generously share everything, allowing no unreasonable exceptions and not thinking solely of their own convenience. [...] Married love is also faithful and exclusive of all other, and this until death. [...] Finally, this love is fecund. It is not confined wholly to the loving interchange of husband and wife; it also contrives to go beyond this to bring new life into being.

12. [...] And if each of these essential qualities, the unitive and the procreative, is preserved, the use of marriage fully retains its sense of true mutual love and its ordination to the supreme responsibility of parenthood to which man is called.

13. Men rightly observe that a conjugal act imposed on one's partner without regard to his or her condition or personal and reasonable wishes in the matter, is no true act of love, and therefore offends the moral order in its particular application to the intimate relationship of husband and wife. If they further reflect, they must also recognize that an act of mutual love which impairs the capacity to transmit life which God the Creator, through specific laws, has built into it, frustrates His design which constitutes the norm of marriage, and contradicts the will of the Author of life. Hence to use this divine gift while depriving it, even if only partially, of its meaning and purpose, is equally repugnant to the nature of man and of woman, and is consequently in opposition to the plan of God and His holy will.




So basically, following that, any sexual activity which does not give the potential to be fecund is against the purpose of sex and therefore against the will of God. Makes sense, from the basic precepts.

But wow... this, from the Code of Canon Law, really shocked me:

Quote:

Can. 1084 §1. Antecedent and perpetual impotence to have intercourse, whether on the part of the man or the woman, whether absolute or relative, nullifies marriage by its very nature. [...] §3. Sterility neither prohibits nor nullifies marriage, without prejudice to the prescript of ⇒ can. 1098.

(Included to avoid confusion:)

Can. 1098 A person contracts invalidly who enters into a marriage deceived by malice, perpetrated to obtain consent, concerning some quality of the other partner which by its very nature can gravely disturb the partnership of conjugal life.




(There ya go, CeMar. If your wife deceived you intentionally as to her level of sexual desire, your marriage is invalid if you're Catholic.)

So if you're impotent, but not sterile, then you can't be married in the eyes of the Catholic Church. Unless I'm misreading that?
