Im a 24 year old man here. I have no problem talking to girls and striking up conversations. My problem is that if I have to commit to flirting, I almost feel like I internally close off, I just can't really commit to saying things in a sexual manner and stick to it. If I say it I usually have to laugh it off as a joke, but I can never state my intentions toward anything relating to sexual attraction. How do I overcome that? How can I allow myself to bring my guard down and let things become more than just a joke?
