Dear, Beauty lies within and cannot be assigned to any color of skin be it fair or dark.Else you have mentioned everything else correctly. You are a good educated settled guy. You have your own ideas about your life partner and only suggestion that i would like to give is see that that special one should have a similar background like that of yours. Means socially, economically, culturally and educationally too! (Our great grandfathers were very wise in this respect i think)
For sexual compatibility aspect , if possible get her alone ask subtly her views on it . Just do it subtly without being blunt ;otherwise it could backfire .
