learn to talk to guys

i have made an attempt and effort at this goal and found out its quite easy, i’m a tomboy and not into many girly things, love talking about action movies and stand up comedy so i just talk about that and relax and realise i’m not always expected to be the centre of attention, just joining in with conversations with simple few word sentences counts

No idea how ill learn how to do this, is there a self help book about this, I’m terrible, i avoid talking to guys, after years of only talking to girls I’m getting bored, ill start by searching online, looking for books, ask close friends, or just go out and do it

Im a very shy person but when I see hot guys i go crazy in my head but they try to talk me and the convo is kind dull cuz im scared out my mind to mess up I wish I could come up with better convo starters
