Nevertheless to avoid fornication let every man have his own wife. Lest being unmarried, and unwilling to live a chaste life, he fall into fornication. Every Prayer of Manasseh , say Melancthon and Bucer, must include the priest and the monk. I reply that every man means every man that is free, not bound by vow, disease, or old age: for such are incapable if matrimony. Laws and documents must be interpreted according to their subject-matter: they only apply to those capable of receiving them, not to those who are not. To him then who is free, and unbound, and can fulfil the requirements of matrimony, the apostle gives to precept, but advice and permission, that if he fears to fall into fornication he should marry a wife, or keep to her that he has already married, rather than fall into any danger of committing such a sin.

But such kind of advice is not relished by all that pretend to be reformers. And return together again. Yet I speak this by way of indulgence, of what is allowed to married persons, and not commanded them, unless when one of the married couple is not willing to abstain. (Witham)
Some people think that this was written primarily for priests, but judging from what follows, this cannot be right. If he had meant it only for priests, he would have said so, but throughout this [chapter] he speaks of persons in general. Paul permits marriage as a concession, but the very fact that it is designed to avoid fornication shows that he is really trying to encourage virginity.
There would be no adulteries, and debaucheries, and prostitution of women, if it were known to all, that whatever is sought beyond the desire of procreation is condemned by God.
He added immediately, "Nevertheless, to avoid fornication, let every man have his own wife".
