If I didn’t resist physically, is it still rape?

Yes. Lack of physical resistance does not mean that a rape did not occur. Sometimes, physical resistance may lead to increased violence during the act. Non-resistance does not equal consent. There is also a misconception that there are only two responses to danger: fight or flight. However, there are actually a variety of automatic survival responses that may come into play during danger: fight-flight-freeze-faint. Freezing is just as natural a reaction as fight or flight.
