All questions about thinking of erotic stuffs

So us humans are aliens to other aliens.

Have you people ever had those pervy or erotic thoughts going on at the back of your mind while conversing?
As for me;I just can't help but imagine weird scenarios' of people doing ecchi things, while I pretend to listen to my cousin nag about her bf or when my mom asks me to do stuffs.

P.S: I'm not in the scene, only men are doing each other!!!
