Confused

I would like to have oral sex it would b my first time any advice

if you are giving it and not sure of what to do; best thing is just straight out ask the other person what they like, and during it ask what feels good and what doesnt, you should be able to tell from the noises and body movement they make though. If you are not in a mature enough relationship where you can ask your partner these sort of questions then you two shouldnt be engaging in sexual activities.

If you are wanting to receive it, and it's your first time, make sure you are clean, have a shower before hand or something, and trimmed at least. Find out what feels good for you, know one knows your body like you do, as you receive it tell your partner what you like and what feels good. Enjoy it and practice safe sex. Good luck.

same here I need help with that I want to but I just don't know what to do

I do believe the girl said she wants to have it, not give it.

Do you mean giving or receiving?
