just me?

So I've recently had sex for the first time after 8 months. The guy that I had sex with has an 8 incher, 2 more inches than my ex! During sex I got dry a few times but we kept going. I think that it resulted in scratches in my vagina due to friction. Now the inside of my vagina is itchy and I have been sore for going on 3 days. Is it normal for this to happen?
