I'm 5'10, and in college was seeing a guy who couldn't have been more than 5'3. Well I didn't really see
him, more the top of his (kinda flaky) head. I didn't really encourage him, but I could never see him coming. He'd see me from across the room/campus/other side of the country, and by the time I was aware of his presence, he'd be there, gazing at my ....well, anyway, I was not comfortable.
He was also a bit of a jerk. But hey, I was 17, what did I know?
My partner is 6'3 and suits me juuuuust fine. He's a fine, fine person, very handsome, intelligent and good motivation for using an anti-dandruff shampoo.
