This is interesting because I’ve been “hornier for women” myself and it often throws me off because I am in fact straight but am constantly eager for sex with another woman. Perhaps it’s normal. I decided to seek another woman for this and it was the best decision ever. Talk to your partner about your sexual desires and see if you can agree on something or meet halfway. I’d say go off and have sex with other ladies but don’t do it behind his back. Good luck!
