It's time to learn to speak truth and negotiate with him.
Don't begin confrontational. Instead use the words I and me and express what you really want to him.
For example: it's important to me, please try to understand that I want us to have more outdoor time together.
And since you feel objectified, tell him the feeling, like "I know sex is important to you, but I feel objectified. Can we have another approach? Like... (what you want while having sex)..."
And yes, negotiate. Get him to voice his needs. Obviously he wants sex. What else? Ask. "I hope to know your needs better. Please tell me while having sex, what else can we do? (what objective?)"
Key principle: Share feelings, open expressions, no judgement, empathy and then set boundaries.
To conclude, before you decide to break off, give him this final chance for an exchange of emotions. Then see if there is hope for better a relationship that his needs are satisfied and you don't feel objectified.
With words. Your not here to find out how to end a relationship your trying to find out how to do so in a way that gets back at him. Quit being a child and leave. You want to vampire a feeling of power by hurting him. The truth is that your probably not relationship type, if all you have to offer a man is sex, that's all he wants.
Communicate what you are thinking and feeling otherwise he won't know. If he does not change then just tell him you don't see yourself with someone who isn't taking your feelings and serious conversations into consideration

I believe that a man's primary responsibility is to serve, glorify and worship the woman he's dating, unless he's a weak beta male whom she has no intention of allowing to have sex with.
women objectify themselves what do you expect
Do you not objectify him?
