Questioning...

So recently (in the last 2 months) my husband and I have opened our sex life to 3somes.I love seeing him dominate another woman. I have never been with a woman other than kissing. I have always admired a womans body and I love curves.I have never been sexually attracted to a female. Well now I am questioning my sexuality. I am labeled as a "pillow princess" I receive from females but I have had no desire to return the favor. I love men and penis. But Im starting to think like... What's the big deal of returning? I like getting so whats the big deal about giving? Ive never been up close and personal with another females cat. Im nervous but the idea doesn't gross me out. My husband thinks Im Bi curious... I don't know what I am but I feel like its not normal lol... any advice or tips would be appreciated.. KEEP THE HATE AND JUDGMENT TO YOURSELVES!
