For shure make the first move. If guy have never kissed and he likes you then its nearly impossible to kiss you first since it takes a lot of confidence, yet guy dont have confidence that comes from experience.
Not so long ago I never had kissed a girl too and then this girl kissed me first. We were watching movie in her bed. It was nice feeling and I went hard first time we kissed, but I didnt know how to kiss, but she teached me the way she likes to kiss. Been using this experience and kissing with girls ever since. I was lucky that first girl made the first step cause girls afterwards didnt made first steps so I had to be the one who starts. I would kiss few more girls from eralier in my life if I knew how or had the experience.
If you want to then kiss him. Should be easy for you and you both could enjoy it. Think you will do him a favor by going after what you want.
Doubt kills more dreams than failure ever will
