I'm not as good at flirting as other types, so I try to avoid it. Light flirting can be fun, but I'll never get carried away with it because it won't be as fulfilling as other people they've flirted with. The thing with being an ISFJ is that I don't let my feelings out that much, so it feels pretty special to just tell someone straight up that I like them. Which from previous posts, seems to be the way that most ISFJs feel.
Plus it also seems to me that most ISFJs are very storgic lovers, meaning that they don't play games. They are all about sincerity and commitment.
