Tell him you want nothing more than to make him happy for Vday, meet him at the door dressed like a stripper, bathe him, fuck him, cook dinner while he watches his favorite TV show in peace, eat, go change into round two outfit and repeat. Let him sleep drained and happy.
Or Dyers 671 blower, Carbon fiber handlebars, Hifonics 500 watt amp, Slayer discography, ect... will blow your mind. Most women cant even comprehend what we want most times when it comes to presents but you cant go wrong with hot sweaty bark like a dog sex.
Use the KISS (keep it simple stupid) and go with the first option.
