First time anal advise please !!!

hi

Hubby and I been together 12 years , married for 7 . He takes great care of me and makes sure I am always satisfied. He really wants to use a butt plug on me but I’m nervous !! I want to get kinky with him I love him so much !! We have a baby on the way and I am Horny AF! I ordered so much stuff from Adam and even I just wanna get freaky lol

How should I relax about using a butt plug?! Any advise . Cleaning , inserting . And honestly , does it feel

Good ????
