Therefore the sastras enjoin that one may have sexual intercourse only if married and only for procreation. Otherwise it is illicit.

>> Ref. VedaBase => BID 13: Freud

Reverend Powell: Thank you. I take it from what you’ve just been saying, Your Grace, referring to illicit sex as being anything that’s not in marriage and not for procreation within marriage.

Prabhupada: Only the sex allowed only for begetting nice children.

Reverend Powell: Yes. You don’t feel that…

Prabhupada: And beyond that, sex, that is illicit sex.

Reverend Powell: And that is out.

Prabhupada: That is not good.

>> Ref. VedaBase => Room Conversation with Reverend Gordon Powell – June 28, 1974, Melbourne

Guest (1): Well, in this present world I think, you know, sex is not for procreation, it is more for fun. I think ninety-nine percent of the couples who indulge in sex do not think of children at that time.

Prabhupada: But that is sinful.
