Are these comedic conventions based on reality?

I noticed recurring references in film and TV comedies to two things that puzzle me, and I’m wondering if they are based on reality or are just show-biz conceits.

First, I wonder about “daddy issues”. Supposedly, most younger women have them, and unscrupulous older men can exploit them to get in said women’s pants.

Second, what is the deal with sweatpants? Supposedly, when a woman wears sweatpants, she is signaling to her husband or SO that there will be no sex that night, and he shouldn’t even try to get her in the mood.

I’ve seen plenty of film and TV gags based on these notions, e.g. in mediocre sitcoms like Two and a Half Men or How I met Your Mother, but I’m skeptical. If you are male, have you ever used “daddy issues” to your advantage? Have you observed a correlation between sweatpants and no sex? If you are female, do you or someone you know have “daddy issues”? Do you wear sweatpants when you want to let your partner know he won’t be getting any that night?
