OK, I'll freely admit that from a physical standpoint, I'm more of a so-called "breast man" than anything else. However, I don't like women with huge implants like Pamela Anderson (I actually saw her recently in a Home Improvement rerun, and she was fine before the "upgrades"). I prefer a woman have enough "up top" so she fills out a shirt appropriately, but not to any real extreme (Jennifer Love Hewitt, Lacey Chabert, Beverley Mitchell, and Allison Mack are good examples, in my opinion).
I truly believe that looks aren't everything, however. When it comes around to personality, I find faith-believing Christians the most desirable, because usually they exhibit a degree of selflessness, responsibility, and spiritual maturity that doesn't exist elsewhere. Ideally, I want a wife someday who is not just beautiful, but also smart, caring, kind, confident, patient, and understanding. Definitely not into pushovers, but I don't want someone so bold that I widn up being controlled all the time.
I guess it's like the old saying of "Men are attracted to women who remind them of their mothers". In truth, men generally want someone who will honor, love, and respect us like Mom, but not order us around like our parents did.
