Is it normal for a straight 25yr old man to have sleepovers with friends often?

Its usually called passing out at a friends place but otherwise sure.

Just as long as you don't suck each other off

Do you read scary stories? Lol, I mean, I've had friends stay over, or stayed over at a friend's place at that age, usually there's drinking and drugs involved so driving around after was a bad idea anyway. I'd say it's normal.

I get stoned at my boys house all the time. If his girlfriend isn't home, sometimes I'll crash there. I'm so comfortable with him though because he's pretty much my best friend. I've slept in his bed before too and we've cuddled being high out of our minds.
