First kiss in a week :)?

Alright so I've liked this boy named Joseph since a few months ago, then Joseph finally asked me out not to long ago. Well both Joseph and I got invited to my best friends party which is on the 18th. My friend was planing to play Manhunt so her and her boyfriend could go out in the woods and be alone. She knew that Joseph would come if I went so she invited him too. When Joseph found out we would be playing manhunt and that we would be on the same team hes texted me "hey Kayla knowing that we are on the same team maybe we could have our first kiss in the woods ;)" the only thing is I'm really shy and I'm kind of nervous because I've never kissed anyone. Joseph never kissed anyone either. How can I make myself less nervous and do you guys have any first kiss stories? Thanks :)
