OK, well is she is screaming and is wet. I guess that is a good indicator that things are going well. Unless she is a good faker? I think most women like the more the better. And they hate to be rushed.
Are you telling her that you think she is good in bed? Are you telling her positive things? Reassuring her?
I have read that women have a serotonin release during the big O that causes a woman to bond with her man. Are you holding her afterwords to bond with her? I think men do not have that chemical release only women.
Anyhow, sorry I do not have any more insight here. Eventually when you marriage is in a better spot and she feels more secure with you- I bet then you can experiment more and she may be willing to talk more openly.
