Does one have to confess using a condom with a hooker, or would it suffice to simply confess the sexual act? As a practical matter, using a condom with a hooker would be advisable-- of course I do not sanction having sex with hookers!— one may reasonably say that it could be more potentially dangerous not to use 1.
Using the species as given by St. Thomas Aquinas, the use of a condom is the species of
unnatural vice. St. Thomas defines fornication as *normal *rather than unnatural. The
unnatural vice includes uncleanness (effeminacy), sodomy, bestiality, artificial birth control, etc. (I suspect that most people are not so logical in assignment.)
His species of lust, are given in the
Summa Theologica Part 2, 2.“These species are differentiated on the part of the woman rather than of the man, because in the venereal act the woman is passive and is by way of matter, whereas the man is by way of agent; and it has been stated above (Objection 1) that the aforesaid species are assigned with regard to a difference of matter.”

Rephrased summary:
153. Lust
Lust is the vice of indulging in unlawful sexual pleasures, which is not always lustful or sinful. There is a good and virtuous use of sex in marriage, when husband and wife perform their normal and natural function of sex without any inordinateness (that is, without anything that is in conflict with reason) and, therefore, without employing any unnatural or artificial means of thwarting the natural effect of their action. The only lawful and chaste use of sex is its lawful use in marriage.
154. The Parts of Lust
The parts of lust are the species or types of lustful sins which are six: simple fornication, adultery, incest, seduction, rape, and unnatural vice.
Fornication is the normal, but unlawful, use of sex by an unmarried man and an unmarried woman. …
Adultery is the normal, but unlawful, use of sex by a married and a single person, or by two married persons, who, however, are not married to each other.
Incest is the use of sex by man and woman who are related by ties of blood, or by affinity, that is, by relationship arising out of a marriage
Seduction is the violation of a virgin.
Rape is a species of lust - and gravely sinful - in which force is employed in committing a lustful action.
Unnatural vice is any lustful perversion of normal and natural processes for procuring sex pleasures.
“Lust, by being directed to another vice as its end, becomes a species of that vice: and so a species of lust may be also a species of irreligion, as of a higher genus.”
