Scared to have sex again

I had a really bad experience with sex in May and I haven’t had sex since. I’m really scared to even do it again. I don’t want to risk having a panic attack or reliving that experience again. I don’t really know how I’ll react when the time comes. I honestly just want to cuddle and kiss someone, I’m really turned off by the idea of having sex or having someone inside me. But I want to eventually enjoy it again.

But should I tell the next potential person why I don’t want to? I feel like that’s a lot of baggage to put on them. Idk. I feel lost. Please help.
