First time...

So my boyfriend and I have had a long distance relationship for the past 3 months. We’ve sent pics and talked about sex quite a bit. We are both virgins, and I really want to have sex with him. But I’m still super nervous that I won’t know what to do or do anything right. I’m even nervous about kissing him because I’ve never done anything besides a few pecks. Am I just worrying too much? Any advice will be helpful. Thanks!
