Advice needed!

Lori • Happily married for almost 5 years and really wanting to have a baby
I have a friend that constantly complains about her sex life.. She says it has become a routine and I told her maybe they could try having sex anywhere but the bedroom.. Her reply.... "Ew that's so gross! Like sweaty gross" Sooooo I don't know what to tell her anymore lol seems like she doesn't want to change anything 😕 any positive advice I could give her???
