It depends on what stage of life we are at, and whether we are emotionally healthy, etc. For example some guys are looking for someone to mother them (I can't think of anything worse!). Other guys will just look for sex, especially when they are younger and immature. Despite this, I think that women might be surprised at the number of guys that are looking for a genuine relationship.
I am attracted to women who are being themselves, are independent and genuinely happy. My ideal relationship would be one where we accept each other, communicate well and work towards common goals.
Basically I think couples need to be on the same wavelength and work together, not against each other.
My worst nightmare is a partner that relies only on me to make them happy, complains a lot, or tries to change who I am. (Although it's ok to take off a few of my rough edges lol)
Initially I am attracted by a lady with nice eyes and a nice smile:)
