Is it wrong

I’m married and I do masturbate and watch porn only when I masturbate. when my husband is at work. Not because he doesn’t please me but because I was trying to make myself squirt.(which I succeeded in) and it feels good. he knows about the vibrators because I bought him a “clone a willy” gag gift and it came with two vibrators with it. And I told him I masturbate sometimes. I guess I’m embarrassed for him to know? And a feel a little guilty? Am I wrong?
