You should do what you want to do. You should not feel pressured into doing anything you don't want to do. If you want to dress more sexy but necessarily more naked, then go ahead. I dress sexy for myself sometimes, just to feel good about myself. However, dressing or undressing to allow men to see your so-called physical assets can go both ways. 1. It can make you feel good that you can still attract other men 2. you feel cheap about the whole idea. Thus, you don't have to dress sexy all of the time but just occasionally in front of him. I see no harm in it but if it makes you feel bad or cheap, then don't do it. As for posting nude photos online, that is up to you too! It is your body and life and no one should dictate you to do things you don't want to do. It sounds like he just wants some of his fantasies played out in reality. You should decide whether you want to play or just say nay.
