An expensive dinner in a flash restaurant is a core part of Valentine's Day for many people; sexual intercourse with your loved one even more so. If you're planning for both, we suggest having the sex before having the meal.

It's not a new concept, but this idea is particularly well-expressed by advice columnist Dan Savage in a recent episode of his Savage Lovecast podcast (note: audio at that link is NSFW and we've deployed some strategic asterisks in the quote below):
My standard operating advice is: f**k first so that you don't have to send me disappointed emails on February 15 or call with disappointed-sounding voices because you went out on Valentine's Day and you ate a bunch of heavy rich food, ate an enormous desert, drank a bunch of wine or booze and then surprise! You didn't get laid when you got home because you were in a food and booze and oh-my-god-it's-late coma. Don't make that mistake. F**k first and then go out to dinner.
Yes, this can be tricky if you don't have a late dinner reservation, especially when Valentine's Day is on a weeknight. But the effort is definitely worth it, satisfaction-wise.
