Another thing to consider: It might just be, that sex being more of an taboo (without the internet being there to inform yourself!) made it more interesting.

Sex is beautiful, but I would always prefer a meaningful human relationship with common interests and good communications without sex over an sex-filled relationship without the rest. Or to put it simply: Love without sex is greater than sex without love. Prefarably both, but it is a thing two people need to want : )
