have you written him a little note for your friend to give to him?
dont make it a long one, just something simple maybe?

hi, im excited to meet you!

something to try to make him not nervous some how
i always try to relieve the tension as quickly as possible... but thats just me... but the biggest thing i do is run away so that wont work here!

i would like it if girl sent me a note with some intentions first, that way i wouldnt be walking in blind
