We do ... My wife and I often wear matching lingerie under our work clothes, not only panties, but bras, garter belts and hose. What a turn on that is for both of us on those special occassions, including when I am at work and she calls and describes in intimate detail what I am wearing, which she knows because she is wearing the same lingerie too.
Ladies can get there men to do anything they want, where theres a will theres a woman makeing him do it. Be sides you would be really surprized on the benifits it raises on him. If you like him ready all the time and 2 to 3 times a night. Go play with them on him, let alone you may just love the oral he will crave.
I think it is impossible to know, especially about the innerware.
