I dated a guy once that was the same height as me, i didn't like it, i couldn't lay my head on his shoulder an i didnt feel secure if i hugged him cause i was looking straight over his shoulder, jus didn't like it.
Right now i'm 5'4, DH is 5'10, i dont see myself wearing anything over 4 inch heels anytime soon so we're fine. He always complains that he likes when he can put his chin on top of my head and if i'm in heels he cant do that but he still likes to see them and he keeps on buying them. LOL.
