Do you think I'm a nymph?

This is my second marriage. My last marriage was an open marriage. I had four regular male partners and my ex husband. I wasn't happy in that relationship. There were lots of but no love. I'm now happily married to a man ten years younger than me. He has high drive, but very jealous and possessive. life with him is good. We have at least twice a day. But when he's away often find myself masturbating with toys and fantasizing about him. Last month he found out I secretly have toys and he was very unhappy about it. Pretending to be a good wife I made a promise I couldn't keep. I still have my toys and I play with them when he's at work. I know if he found out again he will not trust me anymore. I do you think I'm addicted to sex ?
