I've never been sure if lingerie was automatically expected for a visit, know its not a must but a nice touch. I or my client may buy a piece and i will only wear it for that client. If I use one of said outfits for a photoshoot and a gentleman request it then I don't mind at all. Men seemed to get excited when they see the outfit in an ad, I love it.
Being a visual person I see these items as memoirs, using the same outfit for different partners seems too much like acting the same play time after time. granted I keep them and I look at them from time to time or if I'm being girly playing dress up

Sure I'm not going to do it for a short appointment unless its from my client but in my opinion if a guy is spending $300+ on me, it won't kill for me to splurge to know that image will forever be burned in his brain. That's a huge turn on.
Side note, my most intense moment with fashion and passion was my date brought me a breathe taking piece from agent provocateur, I really thought I was going to have a heart attack due to his fantasy was to rip it off me. I admit I wasn't sure whether to cry or have a screaming orgasm.
So...Is it really that weird?
