My boyfriend thinks my body is just an object for him to do anything he wants to do with.

I think I've finally found another guy that I can really trust. I'm 18 year old woman and my boyfriend is 20. He's never talked about body-shaming me or taken any control over my food habits. But there is something that he does that I feel is very wrong. But I'm not sure if I'm just overthinking it.<br><br>Me and my boyfriend have sex regularly, often around 4-5 times a week. Maybe once a week, we will do it when I'm not in the mood. I don't really notice any difference between when I'm in the mood and when I'm not. Also, my body is pretty skinny and my breasts are not really big, but he's never really complained about that.<br><br>My boyfriend often gets in the mood for sex without warning and he just gets behind me and grabs me by my hips and starts rubbing his dick on my ass. And I can see he's already hard. He does this when I'm working, cooking, eating, or doing pretty much anything. He does it so frequently that I've gotten used to it to the point where I don't really even notice it.<br><br>I don't find this act pleasurable, but I also don't find it uncomfortable. It just feels like a minor inconvenience. But sometimes I feel that he's crossing a boundary by doing this, but I'm not sure if I'm overthinking it. But I feel like he's treating my body like it's a sex object, something that is at his disposal to do anything he wants with. Also, I feel like my consent is not being respected. But at the same time, I feel like overreacting and complaining about this to my boyfriend is making too big of a deal about it. I feel like I want this behavior to stop but at the same time, I don't want to make a big issue out of it.
