This is not to say that normal guys can't make good lovers, but they are more likely to cause drama. Of course, I can't speak for all of my kind, but for the most part it's true.
Most geeks are kind and understanding.
This is because we understand when our girlfriend/boyfriend is feeling down and actually care.
We know how to be respectful.
Most geeks will not say rude things like "hey baby!" or do the attraction whistle.
We are willing to learn anything you want to teach.
It is very difficult for us to find a woman/man that is willing to put up with us, but when we do, we won't say no to your interests if you know what I mean.
As long as it's reasonable.
Geeks make better fathers/mothers.
Once we start having families, we actually spend time with the kids instead of sitting inside watching football all day.
We struggle at first, but eventually have more money.
Geeks are incredibly persistent when it comes to their goals and life, and are willing to do anything to achieve their dream.
We are willing to learn to perform better sexually.
This one mostly applies to men, but can apply to women too. Many guys who suck at sex don't bother to improve, but a geek is always to better himself, and sex is no different.
When tend to produce smarter children.
When we have kids, they often inherit of high intelligence and are much less likely to become problem children.
We tend to apply the things in our hobbies to real life.
I know this doesn't sound like a good thing, but it can be if you know what I'm talking about ;).
A geek will try his/her very best not to hurt you.
If this does happen, most of the time it is unintentional. We are willing to face are own mistakes and apologize rather than try to make it look like you are to blame.
Geeks will actually pay attention when you talk.
Some guys don't care about what you have to say, but we do especially if the talk is something we are familiar with.
