If you mean the Catholic Church, that is incorrect. That teaching is that sex is good, sex is not a sin by itself, but must happen in the correct context of a mutually consenting married couple and must be ‘open to conception’ (i.e. no artificial changes to the procreative ‘mechanisms’, such as condoms or birth control.) They even teach ‘Natural Family Planning’, which is basically how to enjoy sex in rhythm with woman’s fertility cycle so as to ‘naturally’ avoid conception.

Not practicing Catholic anymore but that’s what I was taught from the Catechism et al several years ago as a convert.
