Easiest way just go random and talk with girls,about anything (time,weather and ….) in my life I date plenty girls,now married 15years For me was same I was scared of girls can’t talk at all,but once I got a bet with a friend,and I did it,talk once talk second time … and every time was much easier.You can’t build confidence in one day ,it’s taking time.If you text girls on “Tinder “ and if you know you going date her,just tell you are stammering,just be yourself,in the world is billions girls-women’s,I can bet you can find right one!! P.s Sorry for English is not my first language
