Why is it spoke like some kind of horrible thing?

I want a gf who feels happy with me. I want her to have fun. I want to build her up when she's feeling scared. I want her to feel more self-confident because of me.

Yes I'd like to tease her and even dominate her in the bedroom but only if she knew it wasn't real and that her boundaries are respected. I want her to feel wanted and desired and eventually loved.

Why is that a bad thing?
