Had to lie about my sexuality to get a guy to understand I'm not attracted to him or other men.

I had to lie and say I was a lesbian to a guy that is my male friend. I believe, secretly, he has a crush on me but even so, he asked me "Why I wasn't attracted to men?" and I said "Girls are prettier than men". I meant that in an aesthetic sense, but obviously I'd rather him think I am a lesbian than deal with having to explain my actual sexuality at the time, because we were on a carnival ride during that convo.

Any of you guys had to lie about your sexuality because it was too complicated to explain at the time?
