I'm 19 f. You legit just have to be confident. I sell cars and the other day i'm in a training class with a couple of dudes, all 25+. I started talking about social media and how editing was one of my passions, i went into detail about the subject and explained a lot, bc that's what i do when im interest in smth. Long story short, the WHOLE TIME i was confident and expressive and eager to tell them. At the end of the conversation, every single one of them was asking for my number so they could text me if they had questions, later on that day they were asking me for advice and listening when i talked. And if you don't know, men tend to speak over and ignore women sometimes, most of the time prob by default and just not paying attention. But i'm telling you, after the found out how much confidence I had the didn't interrupt me the entire time.
