Yes! I just had this dream last night that my penis was detachable. I believe this is the third time I've had this dream. Every time it's the same it's so weird because of the way it detaches. When it is detached I can still feel it, pee out of it, and jizz out of it. Also when I try to detach it I barely have to tug on it and it comes right out of me, but if someone else tries they can't get it off at all. I wonder if this will change in the next dream since now I am discussing it.
In my dream last night I was having sex with a girl who apparently I knew but I couldn't see her face in the dream, but I was already really horny when we started and I was like no I'm gonna jizz right away, so she jerked me off and then I pulled my dick out of me and fucked her with it backwards, so the spermed end wouldn't be going inside her and she wouldn't get pregnant. So in this dream I didn't really think about it being detachable until this happened. After that happened (still dreaming) I thought about it being detachable and was worried it could fall off easily. I thought about texting my friends and asking them if they had a detachable penis too.
Weird shit. No idea what it means, but I am currently in the process of restoring my foreskin, might have something to do with that, although I know I've had this dream before I started that.
Now that I think of it, I'm pretty sure that in every dream I've had about my own penis since hearing the song detachable penis, my penis has been detachable, whether I detach it in the dream or not. The option has just been there in dreams since hearing that song. I can remember some dreams I had off penis as a little kid, before hearing that song, and my penis was absolutely never detachable back then.
