is this rape?

So my boyfriend and i are stranded in a different state because his car broke down. We are staying in a hotel and he’s been taking his bad mood out on me all day. He’s been pretty much ignoring me for the past hour and went to the bathroom. He came out and was like “bend over”. I told him no multiple times but he proceeded to continue taking my pants off. I told him no again and he literally just stuck it in. I keep telling him something is wrong and it’s painful and uncomfortable to have sex. (i have went to the obgyn and all the std/sti tests came back negative) Yet he still continues. It happens all the time. Sometimes he will get pissed and guilt trip me into it, others he will just ignore me and keep doing it. I hate it. We will have sex and he will want more an hour later. It pisses me off and makes me kind of sad. He makes me feel obligated every time he wants anything. I feel like an object.
