Bi-curious? Need advice, please!

I am happily married to a man for 12 years now. I know that I don’t want to sleep with another man but I really do want to be with a woman sexually! My husband and I have had in-depth conversations about it and he seems to be totally okay with it! (He wouldn’t be involved with her at all.)I finally met someone by chance!! that does sleep with women and she is in a long term relationship with a man. Anyway, she likes to flirt with me and knows what I want and know I’ve never been with a woman!! But if the situation arises I think I would either chicken out entirely OR if it did happen feel guilty about it! This is something I’ve always wanted to do! Anyone else in my shoes? lol my husband is my best friend and I wouldn’t want anything to happen to our relationship I guess is my biggest fear! Any advice?
