You don't have to wait 'til Valentine's Day to give your boo a bunch of roses. Why not start giving them one every single day from February 1st all the way up 'til the Valentine's or the last day of that month.
Roses ain't just for women. That's just a stereotype (well, in my books, it is). So give ya man a rose, dammit. Rose him the heck out. :-)
After February's done, why stop there? How about giving him/her a rose every week for the rest of the year? Make it a romantic habit.
