Our Cat Won't Let My Husband and I Cuddle

Long story short, one of our cats is very protective of me and hates us being intimate.

Every morning, she will sprint to the bed for cuddles when I wake up, then leave after a few minutes. However, she will then come back and sit on me or inbetween us if my partner and I start to cuddle or I try to start having sex when awake.

Our cat also gets very defensive if my partner tries to get into my hole when I'm asleep. I've told my partner he can do it if he wants. Our cat however has attacked him the past three times he's tried. Apparently, she will meow at him and swat at him until he gives up.

Any ideas on how to let our cat understand we are okay or that it's personal time?
