TIPS: 22 and just got my first dildo!!

So I am a late bloomer. I've never had sex, but have masturbated with fingers but never with any toys. And I've decided I wanted to experience it. I've tried my new and first dildo once and I'm just really tight. Any recommendations to relax more? Truly enjoy it?? I'll take anything! (Yes i have lube!) many thanks! ☺️
