Eating out

My friend wants to eat me out, but I've always thought that was kinda weird. Also, I'm self-conscience because I don't know what I'm supposed to taste like. What if I taste funny or something? Yes, I'm still a Virgin as well..... I don't know what to do, I've had the biggest crush on my friend and I really wanna try it with him, he wants to be the first one to eat me out. Help please
