No orgasm, suggestions?

Julie
So when i have sex with my guy it never really does anything for me... It's not that he's small but for some reason i just dont really feel anything. When he fingers me i can have an orgasm but that's it. It's a little frustrating becasue I don't want him to think im not into it or feel bad i just don't know what to do. Any suggestions on what i can do to make the vaginal sex better? Thanks ladies!
