ITS NOT THAT HARD!!! go with the flow.. why have you only kissed twice in 2 months? how old are you?
Ok so let him make the move, or I guess you could, guys tend to make the first move but they lovveee it when the girl does too.
so id say just relax
look into his eyes and when your lips touch close your eyes and just start off with just lips, then start with the toung..
not too much tung at first..
and make sure you dont have to much saliva in your mouth
