I had a problem. I was chatting with one girl she admitted she is virgin and i tried to flirt with her saying something like "you are lucky that you meet expert here i will teach you wanna sign up for first lesson?" as a joke . She got offended really bad. Was is that cringe and offensive seriously? We had a lot of dirty chat ,sexual jokes before so i thought she will be not offended by this. Any tips ? How can i improve flirt,humor? Is cockyness like this cringe ? Any advice will be appreciated
