There are many verses in the OT and NT about being conjugal between a husband and a wife that address pleasuring each other and has nothing to do with only making babies.
1Cor 7:1 Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.
1Cor 7:2 Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.
1Cor 7:3 Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.
1Cor 7:4 The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.
1Cor 7:5 Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
