Problem VI. Why there are some who catch the Venereal Distem∣per at the first amorous Congress, and others do not take it after many, though they have always had to do with the same infected Person.

BY a rational Consequence, we must con∣clude, that if one be more than ordinary hot, the natural parts very porous, and the Venereal Ferment exceeding active, the Ve∣nereal Distemper may be got at the first Coitus. This may happen to a Man who has know∣ledge of an infected Woman, when she has, or is very near having her Months, for then the Venereal Ferment, joyning it self to the menstrual Ferment, which is na∣tural to all Women who are in a Condition of having their Months, does produce a more vigorous effect, which therefore becomes the more malignant, and when there are contrary Dispositions, and one does likewise take care to wipe and wash himself, and to make water af∣ter the Venereal Act, such a Correspondence may be frequently maintained with one that has the Venereal Distemper, without any evil Con∣sequence. But this is not to be rely'd upon, for there are so many particular Disposi∣tions that do concur in this Case, in such a manner as it is impossible to avoid them, or

prevent them any other way then by Conti∣nence, which is the only Preservative against the Venereal Distemper, as we shall shew in the following Problem.
