Agree with RC.
My girl took years to orgasm. A large part of it was shedding inhibitions and feeling comfortable. Some women get there by themselves but not with a partner. In our case, she needed the comfort, the security, and *almost* the permission to orgasm. She still has to be in the right mindset but she still has fun when she doesn't. Sometimes she loves just doing whatever she can to please me and doesn't think about her own needs -- and she always says she loves doing that too.
