Love, in the form of romance: I would include sex in this, since I want to love whoever I'm having sex with. That's not to say I can't have sex I regret, or experience sexual pleasure without "my heart being in it" (Oxytocin is what it is after all), but I dream of having lots and lots of sex in the context of romance, not just having lots and lots of sex. Not that I'm a happily-ever-after kinda guy; I don't expect a relationship to neccesarily last forever for it to be "worthwhile", but I want my heart to be in it, while I'm in it.
Music: Both listening and performing. That I could never live without.
My nieces and nephews, who I love as though they were my own children. I sometimes fantasize about living in a far off land, starting from scratch and making an exciting new life for myself there, and when I think of my family and friends, my heart breaks a little, but I could see myself leaving them behind, and only seeing them for the holidays and such. But when my thoughts go to my 6 nieces and 3 nephews, I cannot bear the thought of not seeing them grow up. I've grown too close to all of them.
That's only four, but those are the important ones. I suppose I couldn't live without a comfy bed either, and a modecum of leasure-time: I don't live to work, I work to live.
Also, If you read Fifty Shades of Grey and either hated it or loved it, I am very interested in hearing from you. I realize this is a dating site, but if you are an english speaking woman, I am working on a novel currently, spurred on by my own very ambivalent feelings about that particular best-seller, and would like to get in contact with some women who would be interested in reading it, to see what they think. It's porn, not great literature, but I take it seriously, and being a straight man, I want to get some feedback from the kind of reader I'm writing to, sorta like a focus group...
Short version is it's a story of a woman who engages in an affair with a stranger, and quickly finds herself in over her head.
