Is it normal to have one sorta- gay fantasy?

okay, so me and my friends were talking (all straight) and one of my friends says to me: "if you had to do something gay with a guy, who would it be". of course, having nothing better to do, i thought about it. eventually i came to the solution that it would either be felix "insert last name here" aka pewdiepie, or andy sixx aka andy biersack. pewdiepie just seems really nice, and andy biersack is pretty good looking, from a hetero point of veiw, and also looks kinda girly. anyway, all i could do is kiss, maybe a handy-J or at the very most a BJ, but even then i might vomit. just want to know if this is normal.

i am straight, believe me. to straight to be gay. although this question doesn't really help, but... yeah.
