Asexual: sex makes me panic

I want to know what other asexual spectrum people think. I’m on the asexual spectrum and recently been trying to date. I want the close companion ship and in theory I thought I’d be ok with physical stuff but now I’m not sure. In my head I’m like yeah sure I’d be ok with sex and kinks, I think I want it too, but the other day I almost went on a date and I panicked cause I don’t want to kiss any of the suitors. And now the idea of having sex makes me panic too. Iv always joked with my pan friend about sex boys and kinks but now that I’m getting closer to actually get to that level I’m panicking cause I thought I’d be ok but it makes me scared. I’m so confused. I am 22 and used to think I was Demi, then gray ace, and slowly slipping to the asexual side.
