So me and my man have been dating for almost 3 months now

He's getting ansi and impatient and wants to get sexual. We have kissed and make out but he wants to go further. I want to but every time it goes to happen I chicken out and get stubborn and don't let him. I want to do this for him but Ive never been fingered or ate out and I'm nervous asf. He also wants a blow job and i haven't done that either and I'm also nervous for that and i don't know what to do. Can someone help me ease my nerves 🙏🙏 plzzz
