i’m inexperienced, help me

I’ve been trying to masturbate while watching porn but I don’t know how, I’ve looked up videos yet can’t seem to get it.

I just learned where the right hole is and can stick fingers in but it just hurts, even while pumping I don’t feel any pleasure at all, it does nothing to me.

I’ve tried an electric toothbrush and the bath faucet as tools which also don’t make me feel anything.
