So you either need to change how you feel about sex and sexuality or just stop doing what you are doing with him. If you can't talk to him about how you feel and tell him that you want to slow down, then something might be wrong with the relationship in general. Being able to just be honest and open with your partner about how you feel is kind of a requirement.
Seconded.
The first time I compromised my morals with my current ex, I started crying immediately after we were done. Why? I had let myself down, in doing something I had sworn to never do. I put aside what I wanted for myself and my self-respect, and I felt pretty bad about it afterwards.
So yeah. Either change your morals and your attitude towards some things, or tell him you're not quite ready to do the things you talked about over the phone. Doing it over the phone without being in the prescence of the other person is one thing, doing them in person is something else.
And as Lorien said, if you can't talk to him about how you feel and your thoughts on things, then something might be up with the relationship.
