simple as that... what is some freaky stuff boys will do by themselves?

depends on the guy i think. most guys as far as i know just touch themselves as you expect. strangest thing i do is i rub my cock under my flat hand sometimes instead of grabbing it like everyone else. but other than that i dont do anything super out of the ordinary. and i think thats true for most guys. tho i do know that some do more freaky stuff on their own.

One time I masturbated in between two pillows, and another time I penetrated a cantaloupe.

Staying up after 0:00.

I once fingered my butt when masturbating wasnt really worth the hype.

malecoded LARP question by big CIA dont fall for it they want your faps

Classic CIA move

don't you know? boys can't be freaky only girls can

To be fair, OP never mentioned fapping. Could be fishing for any freaky stuff, so you might be right.

This is kinda true, Its really hard to grind on things if you're a guy, Also a lot more things happen to work as a dildo then a cock sleeve so you can't really experiment with your stuff, The most freaky thing that I've seen guys say they do is taste their own cum but its not really something that most people like to do, You can also try anal masturbation, I've tried it and it can be an interesting and enjoyable experience but its difficult to do if you haven't done it before and it will take quite a few times to make it easier
