What an irony, most often normal guys complain that their SOs are always playing dead and here you managed to find a girl who is not into dead fish style sex LOL

But I think you can just look for any random woman and tell her not to bother with faking orgasms ;) many if not most women will be supper happy with you as they do not even need to move.

the only issue here is how you frame all that because women may run away screaming if you mention necro sex. So you can present it in some milder terms like you woud like woman to be unresponsive or say that you want her to pretend to sleep and only in the end mention something that she should "play dead".
