Why doesn't he kiss me anymore?

Hey my name is Kimberly and I've been with Richie for about ten days and I met him two weeks ago. We really like each other and had an amazing first date that ended with me giving him a bj in the back seat of his car. We made out a lot on the first night. On the second night he did not kiss me at all he just wanted to chill and have more oral. I hope he is not losing interest. Please Help
