You're not the first guy I've known to fess up to that jealousy. I understand the sentiment. Everyone wants to be desired. Romance novels are built around some pretty heavy levels of desire, for crying out loud.
Being a physically affectionate person, I've been happy enough to oblige a guy I'm dating with that fantasy. They've never liked it as much as they thought they would.
There's a simple reason for this, objectification is NOT desire it IS consumption. So unless objectification is a link you enjoy (and some people do), you wouldn't really like it if you got it. It's not you they objectify-er wants. It is the right to amuse themselves at your expense whenever and however they want. You don't get to agree. You don't get to refuse. You don't get to choose where the line for you is. You get exposed to the world's caprice and some things objectifyers do is downright embarrassing. Publicly humiliating. It's all about them. None of it is about you.
Also, it's rarely the gentle little butt squeeze a lover might give you. They tend to squeeze, grab, and sometimes twist. They know what they're doing is unwanted so they're going to get as much out of it as they can. Hurting you also reduces the chances that you'll fight back. You're too busy getting your breast out of the letch's talons before you're permanent maimed to gouge out his eyeballs.
So it wouldn't be like a gentle little butt squeeze, or brushing against the front of your pants, caressing your beard in a way that a lover might seek to convey desire and inspire arousal. It would be more like some random woman who looks like Quasimodo, is missing most of her front teeth, skin like leather, with tobacco stains running down her chin hairs lurching up to you grabbing and jerking your cock and screaming "MINE!" while you're doubled over because your balls have wisely retreated up into your abdomen. And everyone around you laughs at you and piles on the humiliation. Other guys look at you like you personally are the reason they have to wear steel jockstraps to go to the grocery store. If you had smaller balls, this wouldn't be an issue. And when you leave that bar, there's a gauntlet of equally disgusting women lining up for their turn to have a go at you. And every bit of media normalizes this behavior as not only normal, but promoted it suggests you want it regardless of what you say.
Does that sound pleasant? Something you'd want to happen to you on the regular?
What you want is desire. Not objectification. You want someone that you want to want you back. For your body to be a playground. A source of delight. You want them to want to make you feel good. You want their focus, their tenderness, their care.
