She doesn't have to be a "10" but I must be physically attracted to a woman in order to approach her for the purpose of dating.
Personally I'm not attracted over-weight women but there are some men who are.
As for hair most colors are fine. (I'm not a big fan of gray, or wild colors like Orange, Blue, Green...etc). As for height I would not date or get involved with someone who towers over me! lol
Tattos are also not my cup of tea either.
I'm certain I would not be on a lot of women's most have list myself!
Everyone is entitled to have their own prefereces!
Having said all of the above I don't think one can generalize what men or women are attracted to. One trip to any mall, movie theatre, park, or beach....etc And (you'll see just about every type of person with someone). I guess it's true what they say, "There's someone for everyone".
