Your error is to believe that sex is for reproduction only.
There are two reasons for sex: bonding socially with one or more partners and reproduction. Most mammals focus on the latter, but many big mammals have both, which is called recreational sex. When sexual selection begins to act is to select features that increase your chances of reproduction, but recreational sex also increases your chances of reproduction, so species evolve more diverse forms of making animals interested in sex in general in the same way that they evolve stronger and longer bonds with their offspring.
That’s why we are attracted to big round boobs, long hair, thick thighs or round hips and women are attracted to beards, chest, arms, abs or hips for sex, despite none of those body parts having reproductive roles.
