Should i be afraid, is this Normal?

So I’m kind of a late bloomer, I’m 17 and I’ve never kissed anyone until last night. i was with my new boyfriend and a lot of stuff happened (well a lot of me). We made out, dry humped, he felt me up and even fingered me. Everything was consensual and he was always asking if i was okay and even stopped to calm me down (i have anxiety so i tense up easily). Even though everything was great i just woke up today super scared and thinking about it, probably just because it’s a new experience but idk. Has anyone else had this feeling? I just kind of feel alone since I’m one of the only people in my friend group to be sexual.
