happy, I like your approach. It is sexy and fun and loving without completely selling yourself out, or disregarding what it is that SHE would like for this day.
I don't think you want to cut out all the sexy stuff (which didn't sound too overbearing to begin with, after all Valentine's day has a heavy sexual emphasis already--without you doing a darn thing) because it is a celebration of YOUR love for her, which naturally includes your sexuality. If it makes her uncomfortable, that's her problem. Really, it is.
You have included enough things that are not sexual that will speak to her romantic side, and I don't think it's necessary to emotionally castrate yourself to fit into a box that she prefers you live in.
