Also, even if you do decide to try it with a partner who wants to try your scheduled sex idea, I would definitely not start with sex.

Start slowly, by for example offering to jerk him off, or allowing him to masturbate to your naked body. Try it out slowly, and then see if you’re both comfortable with this type/level of intimacy, before jumping straight to penetrative sex.

It’s a very delicate affair, not just for you, but for the man as well. Having sex with a woman who is unresponsive, and just passively accepting, has a potential to make your partner subconsciously feel like they’re abusing, or even raping, you (even if you explicitly give consent, the subconscious rarely care about rational truths), which has the potential to lead serious sexual trauma.
