I haven't had a 'boyfriend' and not exactly wanting one either. I just have no desire to have an unpredictable, emotionally complicated relationship; it's not a healthy situation for him or me.
All colors of hair and eyes. Different kind of character... But they've all one in common: They're my ex and were a nice toy (for some weeks in avarage)
I never really had a serious relationship. Though I've had boyfriends and girlfriends. Guys tend to be tall and fit (not overly muscular), and gals slightly shorter and having nice shape to them.
I think the only pattern in my relationships physically is that I tend to go out with shorter girls, and I like taller guys. Go figure what you will from that.
