Is it normal for a straight guy to think about other guys sometimes?

So my friend wants to know ya? Just say you a straight guy and you think about girls a lot of the time, ya know you wanna marry a woman one day, bang dem in the mean time, pick up at der clubs. And ya no ya like all dem biscuits with big titties and nice ass!

But like, what if you think about giving the cool tough dude blow jobs, planting a little kiss or like lickin out da asses from time to time? If you like never go through with it, but still thinks about it like 20%% of the time when you gwaan fantasize, it's normal ya no see it? It doesn't mean he even a bit battyman no? Maybe mosta guys feel da same but they just don't talk to someone like ma buddy did to me?
