Didn’t mean single moms as characters, Meant in real life.
If Sydney Sweeney was a single mom in real life, would they cast her as the Vixen in the Erotic thriller The Housemaid?
If Margot Robbie was a single mom in real life, would they cast her in Wolf Wall Street?
If Selena Gomez was a single mom when young, would a record company sign and promote her?
If Taylor Swift was a single mom, would she sell out as many concerts?
If the answer is “no”, that means single mothers don’t have sex appeal. If single mothers don’t have sex appeal, how is a man supposed to be attracted to them?
Note: when talking single mothers, we are not talking have sex with her once and never see again. We are talking dating, relationship, marriage, child with her.
If I understand you correctly, you are wondering if men would date single women more if they looked hot (like, Sweeney, peak Robbie, peak Gomez, etc.). I think if we lived in a fairy tale world where the majority of single women were "hot", yes, men would date them more. I think we all can agree on that. "Sex appeal" is independent of being a single mom. A woman can be very physically. attractive and also a single mom.
However, if you are talking about "dating to get married"; then the answer is no. Most guys would not because of the many disadvantages of a longterm relationship with a single mom (you can google them yourself - but one example is not being able to , in most cases, discipline the mom's child(s); also older women are usually stuck in their ways; not to mention, the higher risk of a future divorce due to having a previous divorce, etc.. etc. )
So in conclusion, if divorced women had the attributes of younger women (e.g., being hot, being fertile, not jaded, etc.), yes, men would date divorced women more.
