Most guys are attracted to Sexy girls but what's point if most cant have one?

People talk about biology and stuff. that we’re attracted to them because pasisng our genes, and chances of having healthy baby etc etc.

But reality is in a group of 100 men, 70 percent or even 80 will not even get to have a sexy hot GF. We’ll end up with average girls. Who probably don’t have any of the BIOLOGICAL signs( wide hips etc) or even breasts.

So what’s the point of guys having strong desire for sexy girls? And even if we are married or have a gf, we continue having desire for sexy girls outside of our gf.

Guys suffer alot because we just have this desire that can never be realized or at least we have a very low chance of it. Do girls suffer in this way as well.? It doesn’t seem so.

Anyways, any ideias?
