Why is that most married women won't admit to their husband that they enjoy having sex more with a well-hung guy.

[Phun Times 727]

why would she, now that your opened the door for her to explore her sexuality she will want to enjoy it to the fullest

That is what I hope for her to do. For quite some time after we began it was not easy for her to discuss her desires but given that what we are actually doing is exploring desires it kind of became a matter of its hard to get you where you want to be if you don't reveal it. Its quite a bit better now in that she has grown more comfortable in discussing what she wants.
