I'll preface this by noting that quality time and physical touch are equally clear signals by my consideration.
From greatest to least: Quality Time
I'm pretty independent, even a bit reclusive at times. If I make it a point to spend quality time with you, I enjoy your company.
I mentally value the quality time the most, but physical touch sends a stronger message coming from me. It probably has something to do with the fact that I don't usually like people in my personal space. In other words, if I'm comfortable touching you and vice-versa, it sends a pretty clear message that I care about you.
Acts of Service
I think it's pretty common to want to take care of things for the person you like. Not really sure anything else needs to be said here.
Words of Affirmation
Okay, I realize that most women will need/expect these from me, I also realize that they are important. The thing is, I tend to forget from time to time that the previously mentioned entries don't make this one unnecessary. So this one's down so low as a matter of aptitude rather than importance.
I'm more than willing to give gifts. Actually, I quite enjoy it. But receiving gifts just doesn't really do anything for me.
