"...I want to express love and I want to eventually get married and life a normal, ooey-gooey domestic life." Man, I feel that one. All I want is a peaceful, simple life. In the case of romantic relationships, physicality before intimacy is to put the cart before the horse in my opinion.
As a result, instead of lovingly binding together, it can often distort and destroy. I do not blame anyone for such a state though. It seems that very few people can navigate it intelligently when biological drives and emotions become the rudder.
Three cheers for hard-won knowledge!
