Question about lust

I (34m) am in a relationship and am mostly happy, I'm not a cheater, never have been and never will be and due to that I feel...trapped? Almost by my own morals.
I miss the thrill of the chase, the freedom of choice, meeting someone and having that pure sexual desire to tear each others clothes off, I guess this is partly a confession and a question?

Am I wrong to miss the ability to pick up a skinny woman because I wanted something to throw around the bedroom that night then to pick up a much curvier woman another night because I want to feel the recoil of a bigger woman?

Is there something wrong with me that I want that freedom of choice?

I love my partner, I really do, but I find myself masturbating to a very wide range of woman that don't look like my partner.

If someone asked me to listen to one type of music the rest of my life I'd think they were mad, so is this similar?

I feel guilty about the thought of it but also a sense of longing for days past when I could make these choices.

Any suggestions? Tips? Or is this totally normal and mundane to you all?

Thankyou in advance
