I believe no matter if you are technical or not, you still can find certain correlation between person's sex and if he or she is technical or not. I understand that there are a lot of gals in tech, but it is less likely to happen to see couple where female party is technical and male - is not. It is just statistics. Just like it is more likely for gals to have longish hair and for guys - shorter one. It is just how current overall earth as large system evolved.

Just like everybody assumed I am boring when I was young and nerdish, same would happen to gals in tech. I bet that if instead of waiting for 13 minutes you would join conversation whoever approached you and your fiance would happily continue conversation with you two. Yes, his initial assumptions were incorrect, but they are based on current expectations. As soon as there will be close to 50/50 female/male ration in tech I bet these assumptions will disappear.

Don't try hard to find samples of sexism. Just join a conversation.
