Is it normal to have incestual feelings?

I know what you mean man I love my sisters feet so bad I just say to her " you look worn out can I do anything for you?" ( I tell her I h8 feet so she always says rub my feet and then there you go just ask your mum if she wants a foot rub

I never had incest thoughts. For older guys and women.
.......... I always found older people pukatronic.
I guess it is because of the thought association:
Young-fresh/old-rot. Never fantasized about my grandmo or my mom or my dad for that matter. But I am kind of sure they did.
But yeah, if I had any younger brothers or sisters I would be in big, BIG
Troubles. BIG TROUBLES.
Normal?maybe. Dangerous and potentially extremely addictive? Sure as hell.
Better not doing it. Absteining and restraining from doing it.
I could end up getting mad if they turn me down and kind of become a little too possessive and basically lock them up or in any other way prevent them from meeting any other fuck buddy. Or even force myself on them.
So after all, I am kind of glad it is not an option. On one hand.
On the other one it makes me kind of frustrated. Because I really have not got any options. Besides my fleshlights. Which I enjoy very much. Even if sometimes my left testicle kind of hurts. If you can see the irony and understand the jokes in this comment you are some sort of genius and I must congratulate myself with you.

I want my great grandmother, so I agree that this is normal.
