I just need to no right now if it does hurt so I can have a least some idea? I no this is a weird question to ask.

Throughout your entire life you never have to do sex unless you want to. Just chill out and wait until you want to.

As long as this is what you're worried about, that's a clear indication that you're not ready, so don't rush it.
