Are Anatomical Sex Toys Haram in Marriage?

I indulged in bisexualism in my younger years and have had relationships with both genders. I eventually met my husband, who alhamdulillah has guided me back to the Deen and our marriage has passed the ten year mark. Although there have been times where I felt tempted to fall back into my past life, ahamdulillah, I didn't succumb. I try not to expose myself to situations or things that can lead to this temptation, but after so long, the urge has come back again (for same gender intimacy). I resorted to purchasing a sex toy that is anatomically female, in the hopes that it can prevent me from acting on this desire for real and actually seeking out female intimacy. Is the use of that earlier mentioned toy (by me during marital intercourse to satisfy myself) considered haram? Even if the toy isn't realistic looking and the intention is prevention?
