Respect or Red Flags? Should I give second chance?

Recently met a guy thru AM and were discussing where we’d stay after marriage and I brought up the importance of having some privacy, especially since it’s a big change. His response shocked me. He said, ‘We won’t do sex in front of my parents for privacy,’ which made me feel like he was missing the point. I wasn’t talking about physical intimacy at all.I was talking about emotional space and privacy as a couple. What really irked me is that this isn’t the first time he’s dismissed my feelings on this, but this time, talking directly about sex made it feel even worse. I was so irritated.When I discussed this with my family, they didn’t see anything concerning about it, which honestly made me feel even more alone in how I was feeling.

So, now he wants to give things another chance, but I’m really unsure about it. I keep thinking, am I overreacting? I mean, he’s asking for a second chance, but I still don’t feel like my concerns have been fully understood or addressed. He did dismiss my feelings before and the way he responded just felt so off. I want to know if it's worth giving him another shot or if I should trust my gut and not let this slide. How can I know if I’m just being too sensitive or if my feelings are actually valid?
