Sakura pretty well seems like a normal girl to me in regards to sexual situations, and thusly would react in pretty well normal ways.
shes been shown canonically to be a bit of a pervert or to have a perverted side so I highly doubt shed be shy, or if she did--first timer-- shed get over it pretty darned quickly.
undy wise like Konahakitten said above as a normal girl I imagine shed have a fair to decent selection of various panties, and such. I also imagine she might have a few choice elements given her best friend is Ino who strikes me as someone who would make sure sakura was prepared for just such an occasion.
Lastly I see Sakura being perfectly willing to be the aggressor in an intimate encounter. contrary to many fan fiction portrayals. She is very much a woman, and was quite willing to hug Naruto twice in front of people, as well as kiss Naruto--disguised as Sasuke-- at the bench. Such a forward nature is someone willing to initiate an encounter and push the issue to its climax.
