I’d appreciate a little help girls please

Okay so I’m the most inocente female you probably know and had never had a boyfriend until a couple of months ago and so we’ve been perfectly fine but one thing is we have been pleasing each other not through sex but other things and he’s been asking me to give him a bj and I have no idea what to do or expect or can even imagine doing it I want to please him because he’s the best thing ever but I’m scared to embarrass myself since I have no idea how to even start I don’t want to choke or have him not enjoy it :( can you guys give me any feedback ?
