Hmm interesting!
I never had a boyfriend before my current boyfriend. For the last 3 years for Valentine's day, he buys me new underwear and bras, as I get rid of the oldest ones. He has always told me that when he goes to Victoria's Secret, he would see guys there wandering aimlessly trying to figure out what size to get. The saleswoman would have to say, "Is she roughly my size? Bigger?" They always seem to get the bigger size.
My boyfriend knows exactly what's my size, so he just chuckles when he sees all the other guys.
He got me a dozen roses for our first V-Day together, and I told him off that I hate Roses (and I still have them..they're dried). Since then, he knows not to get me roses.
No chocolates, no elaborate dinners, no nothing. We hate V-Day, and EVERYDAY is our v-day. It just makes no sense that one day out of the year is when you show your love to someone else, what's wrong with the rest of 364 days of the year?
I flatly told him that I will refuse engagement if he asked me to marry him on Valentine's Day (why do I need a HOLIDAY to be engaged?!).
