Is it normal that i'm really into tentacles?

I have it too. As long as you don't buy an octopus and try to have sex with it, you're normal.

Very popular in Japan

Testicles are less painful than tentacles.

Are you Akidearest (YouTube)?

Uncommon, albeit weird i guess but relatively normal.

But i'd say not willing to go to the extremes is probably a good thing as tentacles in general is one thing but going so far as to try to get it on with a octopi? I'd say not.

Although i can't be a judge of 'how weird is this' in general since i'm on the same boat. But the degree of interest or what one finds so fascinating about the idea of tentacles might/does vary from person to persom.
But as long as you dont plan on experimenting with octopi in the future or at all i'd say this is relatively normal.

Are you talking about hentai or real life tentacles?
Either way, it's not really an uncommon fetish since Japan has a ton of porn of it.

You are sick..
No... Just kidding.. it's a normal fetish..
You might want to play safe by studying about the octopus you have on yourself.

Btw. I find you sexy cause of your fetish...

So then, I gathere you are a female?
