long distance

I'm not comfortable with "dirty" talk, so how do I have phone sex?

Regular guy asks:

I've been with my girlfreind for almost 10 months. We have been in a long distance rlationship the whole time that we have been together but we have seen each other at least once a month and just recently spent the entire summer living together. But anyways I just moved back home and I need advice on how to have phone sex with her. Obviously we are having sex and I love her more then I have ever loved someone yet I cant seem to rid myself of this shyness I seem to have on the phone I want to but I am shy and so is she. I'ts hard for me to say the dirty words to her because I've always watched my mouth around ladys. How can I overcome this? I need to know how to initiate, continue and end.
