Should i?

My boyfriend is supposed to come over to my house this weekend and he wants to do stuff. He wants me to give him a blowjob and he said he was gonna finger me and we were gonna make out and give each other hickeys. I really want to do all this with him but i have anxiety and i’m scared about it. That i may mess something up and/or embarrass myself in some way. What should i do? Any help is appreciated!
