having a date today after not dating for a year

hey guys so I consider myself extroverted when it comes to talking but when I have to express myself sexually I feel so afraid.

I broke with my ex a year ago and today I'm having a date with a girl from hinge, she is gorgeous and we will be going on a walk to smoke a joint.

my concern is, when I'm with a girl in this kind of situation sometimes I think man she is so beautiful and instead of saying it I just keep it to myself, it feels like a really difficult thing for me to surpass the feeling of being scared to express this things.

any tips for today?
