I'll make a plug for an excellent book called "The Five Love Languages" by Gary Chapman. Basically, it says there are five basics ways a person feels loved--physical touch (nonsexual), words of affirmation, acts of service, gifts, and quality time.
My primary is physical touch, with a close tie in second for quality time and words of affirmation. Indicentally, the other two--AOS and gifts--don't do so much for me.
More specifically, I love cuddling on the couch and watching movies. I also really enjoy in depth conversations with DH. Also running errands. It sounds silly, but we both enjoy the driving around, listening to music, and chatting. I also enjoy waking up slowly with him on the weekends, when neither of us has to rush off to work, and we can just enjoy each other's company for awhile.
