how do i overcome being shy physically with girls on dates?

[gret3737]

i have been going out with this girl for 3 dates and i dont know if i am going to slow but i have not even held her hand yet and i hope she does not think i only think of her as just a friend. the first date she even brought me back to her room and i did not do anything. the second date was just a small dinner with each other she was not feeling good. and the third date we went to the mall and watched a movie. i was to afraid to make a move in the movie to it did not feel right she still showed a lot of interest in me with eye contact, playing with her hair, smiling and laughing at things that are not funny or not even near jokes. but it seems to have regressed on the first date she was all that but also very touchy and brought me back to her room. i have a feeling because i am being shy and not touching her in the boyfriend way she is being a bit more carefull so she does not get hurt. how do i overcome this shyness?
girls what do you think is this really bad how would react to this. do you think this may end where she will stop giving me chances soon and move on or do you think she understands and hopefully will help me through this? guys i am sure most of you have gone through this at a young age so how do you overcome this? many people tell me to just do it. but just doing it does not seem to be possible then it seems to random at most times to grab her hand or put my arm over her what should i do?
