Sex and spirituality

[WARNING: EXPLICIT SEXUAL CONTENT]

So for a long time I believed that having sex will also connect your spirit with the person you're having sex with. So say that this person has a spirit of greed or lust or anger or whatever, or is actually demonically oppressed, this will now also transfer to you the moment you have sex with them. But I don't know any Bible verses that confirm this belief. Do you guys know if this is true? Or do you have heard stories from people you know that confirm this theory?

And if it's true, when will this "transfer" take place? Only when the climax/ejeculation takes place? Or will it already happen right after penetration (either vaginal or anal)? Also, what about oral sex? Will it then also happen?

This may seem like a troll post, but I'm actually dead serious and I really wanna know. I love to hear from you.
