It is very individualized. Some people like to have sex on a warm summer evening out in the woods. Some people like it in a nice hotel. Some people like to have sex in the backseat of a car. The romance part is one of sensuality, warmness, luxury and all that stuff.
Some people find it nice to have sex in a tent.
We are very sexually active, so active that we have sex almost everyday. But I feel that if we get married, our sex drive will be lost forever because we did it so much before. I am afraid that he will leave me for some one else if we hold out for a long period of time. What an interesting dilemma. If you take a quick check on your genitals, you will see you have an infinite supply of sex.
