I think this guy is interested in me please help he talks to me a lot he asks me a lot of questions my age school grade if i had a boyfriend and he laid down on me?

Firstly, where did you meet him? It doesn't sound like you met him in school etc. And I am sorry to say this, but it seems he is interested... but just in sex. He asked about your age and school year/grade to make sure it won't be illegal. And he laid on you? Where was this? Just be careful.
