When I think about the guys I've liked in the past, they've all been very varied in appearance and personality... The only real similiarity was their passion for God.
I always enjoy being able to laugh with whoever I'm with, so a sense of humour is pretty important. Being kind and gentle is also important, but he should also have a strength of character about him.
The only physical feature I insist upon is a tall man... I'm 5'8, and I'd very much like my future husband to be taller than I am.
