1 Corinthians 7:3-5
"3 The husband should give to his wife her conjugal rights, and likewise the wife to her husband. 4 For the wife does not have authority over her own body, but the husband does; likewise the husband does not have authority over his own body, but the wife does. 5 Do not deprive one another except perhaps by agreement for a set time, to devote yourselves to prayer, and then come together again, so that Satan may not tempt you because of your lack of self-control."

Sex is not Merely for the purpose of Procreation, it's also there to connect with your Wife/Husband.
in fact, if your wife is unable to conceive, then you can still have sex, however much you want really, the problem comes when you specifically go out of your way to lower the chances of conception (which is why contraception method, or medical is not allowed)

but you have to be open to receiving a Child still, in case that it does result in conception, even if it is super duper unlikely.

also note that it is done to please the other partner, not just for yourself, you are servicing your wife, and your wife is servicing you.
