Am I close?

Update: I wound up having one that night! I was definitely way too in my head. My husband and I communicated a lot and I relaxed into it. It was incredible! Thank you all!

I didn’t have sex until my husband and I got married and in the time we’ve been married (less than a year) I have not orgasmed and it’s a little frustrating. When he stimulates my clit, I feel a sensation that starts off as feeling good, but then the longer it goes on I start feeling panicked. Almost like it’s too good if that makes sense. It’s hard to explain! I feel like I’m on the edge, but I’m not sure. Am I close and just need to push through? Any tips?

Note: I’ve tried masturbating before and it doesn’t work for me for some reason
