MIght I suggest playing some music that is not of the "long haired" variety.. you'd probably have a better chance of scoring with the ladies if you play some contemporary music. Unless you find one who's really high class and likes to listen to classical piano music.
My soon to be 17 yo Grand Daughter said when I played Paul Simon's, Sound Of Silence for her and her sister, "Ooh I like that ". My wife loves and I mean absolutely loves David Nevue's, Winter Walk when I play it. My oldest daughter ( the 17 year old's mom) has always loved Fur Elise. My 36 YO daughter loves my arrangement of the theme song Ice Castles. And my X-wife loved my version of Chariots of Fire though I have not played that in 30 years now but when I did she loved it.
So all females liking relatively uncomplicated music. Don't get me wrong, they like other music as well, just saying ! They like it moody, played well and smooth presentation. Bring out what counts in the piece, you don't have to get extravagant with composes etc, IMO.
I have so many females in my life I wouldn't dare even consider calling women cows, or dumb, by the way ! For one thing they aren't either one and I enjoy their company immensely but my Grand Daughters in particular are highly cherished individuals by just about everyone they meet, and all honors students with advanced academic classes. Far from dumb and total knock outs. They will be going on in school on scholarships, the whole family couldn't be more proud of them, myself included !
I know this is different than romantic stuff but then again maybe not so different in what they like for music coming out of the piano..
