At university I took a class about this sort of stuff and one of the eye opening things was the studies about how the couples with the best sex life were actually old, married, religious couples. If you want great sex, then going to church and having a lifelong, selfless, loving commitment to your partner seems to help a lot; but that sure makes sense anyways... There are a lot of studies about how pornography and such also makes it hard to have healthy, connected relationships. Church-going folks probably avoid quite a bit of those pitfalls as well, which helps in the longrun. Also, if anyone is looking for world class research on family/couple stuff, Gottman institute is awesome: https://www.gottman.com/ https://www.gottman.com/
