yeah but it doesn't matter if sex isn't causal. for example, 50% of what determines whether someone is promiscuous or not is inherited through genes:

We may see low heritability, for example in the generally promiscuous red squirrel (McFarlane et al., 2011) or high heritability, for example in the pair bonding zebra finch (Forstmeier et al., 2011). In human beings the heritability for promiscuity is moderate at around 40% (Cherkas et al., 2004; Zietsch et al. 2014), and as high as 60% for men (Zietsch et al., 2014). Again we see the 50-0-50 rule at play.
