I have realized I have hard time keeping girls interested in me for a long time; I guess it is because I am "boring". It's not like I have nothing to talk about etc, I guess it is because I like deep comversations and discussing actual stuff in a serious-ish manner (I am an INTJ if it matters). Also my favorite type of humor is sick, blackish and generally things that people find offensive or rudeish.

Could you help me? How can I keep girls interested in my conversation?
