No Penetration

My wife has not let me have intercourse with her for several years, but she allows me to eat her regularly. However, recently she has decided that I'm not allowed to penetrate her with anything (no vibrator or dildo, no finger, not even my tongue.) I am only allowed to lick her pussy and ass and she always has me suck her clit to make her cum. I know that her and her new boyfriend have intercourse all the time, but she says her insides are off limits to me. Are there other wives who do not allow any penetration from their husbands? I also discovered that she has been using urethral dialators on herself. She said she started using them after she watched an Amazing Ty video and wanted to stretch her urethra out. Do other wives like playing with dialators?

why does she want her urethra dialated?

I'm not sure why, she just said she wanted to stretch it ever since she saw the Amazing Ty video.
