First of all, St. Valentine's Day was FIRST created to honor Saint Valentine - that's it. The problem is, since there were so many saints that went by the name Valentine, it's sort of hard to know which saint they were actually talking about.
Most scholars have narrowed it down to three (3), but that's another story. You can read about it here at http://hub.me/aeE1S
Valentine's Day had NOTHING to do with chocolate hearts, cupid and especially LOVE. It wasn't until great authors such as Geoffrey Chaucer (1343 - 1400) who started associating LOVE with ST. VALENTINE'S DAY.
ABOUT THE GIFT GIVING:
Personally, being a guy flowers aren't really my thing. But maybe a VENUS FLYTRAP would do the trick. How about a bow & arrow set? A sword would be cool... make Valentine's Day gifts a bit more "theme like"... Shakespeare days... Romeo & Juliet stuff and keep Xmas gifts separated from Valentine's Day gifts.
