An additional concern is not being able to find women with compatible intellectual interests (I don't mean having or not having specific interests but being interested and capable of thinking/talking about intellectual topics). Fortunately, there are dating sites. OkCupid seems to trend smart, but there are lots of others too. If you live near a good university, you can also attend evening special lectures and events of that sort that are heavily attended by graduate students. They often have a socializing aspect to them after the event.
