Another gold star here! My husband is too. I'm glad to offer my two cents...
Was it that you had no interest in trying it at least once? Yes. I have literally never in my life thought it would be fun to have sex with a woman.
Did you never have the opportunity to go all the way? Yes. In high school, on my prom night. This, of course, was before I came out. I took a queue from Will & Grace and told her we couldn't because Venus was in my rising house. (I don't even know what that means.)
Were you too nervous to try? Nope. Just never wanted to. Women disgust me. Literally, just the thought of being touched by a woman makes me sick to my stomach.
Were you never curious to know what it felt like? Absolutely not.
