Is he just trying to get something put of me

Im 14 and last month me and my boyfriend were at his house with a few of our friends. I was feeling very rough and had awful periodpains. O was curled up in a ball sat next to him when he pulled me in close and wrapped his arms around me. I pit my head on his chest and he kissed me afew times telling me it was gonna be alright. I was allso crying as we had been watching Romeo and Julliet. He knew I was scared of horror films even tho Id agreed to watching Paranormal. About a third of the way thro the film I was extremely scared. Two of my friends who arent going out were hiding next to eachother. However he then did something I didnt excpect that it made me jump. He put his hand on my chest and began pulling me in even closer. He said he could feel me shaking and thought I was cold or it was the film. I bundled my head into him and shut my eyes. Next thing I knew I had fallen asleep on him. It was about 3pm. When I awoke it was 8 and I descovered that he hadnt moved at all apart from the fact he was hugging me. Our other friends were in his garden. He told me he didnt wanna leave me just in cause I got upset. He tried to lie me down but I wouldnt move. I think he was going too go outside however I was unsure. What eles could he of been thinking whilst trying to lay me down. Could he use this to try and get somethong off me or was he just being sweet. Please help.
