I think I'm a very fun person. Whenever I'm with friends (of both genders) it's easy for me to crack jokes or socialize. I have noticed, though, that when I'm interacting with a girl I'm into, I tend to tense up and become a boring shell of who I really am. No matter how much I try to ease up or think of the girl as another friend, I still end up being a stoic version of myself which inevitably works against my efforts. Does anyone have any tips on how to combat this?
