It sounds hormonal and mental to me. Our minds can play major tricks on our libido too. I used to have intense sexual dreams of women when I was pregnant but I am not normally attracted to women. I found out later that it's pretty common as a result of extra hormones and just my own empowerment because of being able to carry child. I would definetly try the toy idea. Also take a good look at yourself and your life to see how else you have changed. Have fun and be safe.
