I don't know if you want one with lyrics you can sing, but if not try mama im coming home by ozzy osbourne.

This is a fun little blues song I wrote that has a remote chance of being what you are looknig for.

It's about a guy who thinks he has to spend money for his girl to love him but in the end all he had to do was love her.

It's called "'No Kisses Til Sunday"

...forgive my crappy singing and poor recording... this was recorded a while back, when I thought I knew what I was doing.

wounder wall by oasis, pretty easy, but you got to listen to the song to get the right rhythm.

VERY simple and one of the songs in my "bed the babe" set...

Emerson, Lake and Palmer wrote a lot of songs women love. I'd suggest Ces't La Vie. Only 5/6 chords... Em, D, C, B7, Am7 and F#. Lots of picking though. Not just chord strumming. The picking is really easy, however. Just up and down the strings, bottom to top and back.

Simple song that has words to impress and easy enough to include the "key" factor when playing for a woman. You should be able to look into her eyes instead of looking at your guitar!

there are countless country songs to say " i love you ". many of which can be played with mostly G C and D. something by alabama, george jones, or randy travis would be sweet and simple.
