That’s wonderful, you’re so welcome! 45mm is the middle size ring I think? Should be good. The fun thing about the solid rings is they act like a cock ring for hubby too so when he does come out and get hard, he’s really hard.
Just remember to swivel the ring around to the side so the pointy bit isn’t in the way when she plays with you.
Have fun… and let us know how you’re getting on!
