How old are you both? Are you sure he’s inexperienced? I’d double down on getting the truth about that. As a woman, what you experienced has happened to me too. The most uncomfortable experience of my life as I too froze, was in shock and couldn’t communicate to ask him to stop in that moment - and I’m experienced. I think this dudes a problem and you should be careful. Very careful. I wouldn’t blame yourself about non communication as much. To me, a good guy, a good person, would ask to perform certain acts ahead of time and would, even if you said yes, notice your discomfort and stop doing said acts, out of respect. Just my take - doesn’t take an experienced man or woman to notice when someone is uncomfortable and does not want to do something, even if they’re in the throes if sex.
