when penis pulsate

Hey

Why do penis pulsate , I mean sometimes im only 70%-80& erect and it starts to pulsate?

is that negative/positive

I notice mine does this too. I also noticed that it pulsates only when I’m lying in a certain position. I always wonder why it did this.

I think it’s a good thing. It makes me think I’m a super cyborg fucking bot with ultra sexual powers

Hahaha yeah I wish it was like that but it’s not something that’s controlled or that pulsates hard enough to cause pleasure. It almost feels like it’s doing little flexes by itself.

Happens to me as well. I don’t really think of it as a bad thing, maybe it has something to do with arousal? It happens to me only when I’m fully erect.

Sometimes mine pulsates in time with my heart beat, but only when I’m 100% erect.

Are you able to tell if the pulsation is muscular, blood flow, or ligament related, that might help determine. Then again, these things have a mind all of their own, and will try to control the entire male body & it’s ego.

The penis becomes erect because the erectile chambers (corpora cavernosa and corpus spongiosum) fill with blood. Blood flows in arteries. Arteries fill your penis with blood. Blood is pumped through arteries by your heart. Your heart pulsates. Heart -> arteries -> penis. Pulsate.

It stops pulsating when the chambers are so full that the tunica albuginea becomes tight and the penis rigid. It probably still pulsates a bit, but you don’t notice it.

Oh that happens to me sometimes, it’s strange like you can feel the blood flowing in and out or something really quick.

You won’t find a better or clearer description than that!

Heh, thought so. :)
