Can you give permission for someone to have sex with your dead body in your will?

DISCLAIMER: This is not relevant to me nor to anyone I know! It is purely curiosity.

Sex with a corpse is illegal in most states, presumably because it could be considered rape, as the dead cannot consent to a sexual act. But what if you give specific permission for this in your will?

Let’s say you live in one of these states, and your husband is a necrophiliac. He does not act on his desires to sleep with the dead, but it is a fetish of his. You would like him to have sex with your body after you die. Can you specify this in your will, and if so, would your husband be exonerated from legal action if he were to have sex with your body after you die?
