Guys, have you ever fantasized about being with another guy?

I am 37 years old now but when I was 13 and going thru puberty I used to lie down and masturbate on the bathroom floor. I used to have my legs spread open and I would fantasize about my tennis buddy from school fucking me in the ass. I used to go, "pounder, pounder, pounder" ( lol ) out loud as if I was getting pounded. I would cum on my stomach and be done with the fantasy. I hardly think about guys now, except an occasional blowjob ( Me giving ) fantasy. I've never been with guys. Just wanted to know if you all have fantasized when you were younger or even now, and whether or not you acted on it.
