First time sucking dick🤷🏾‍♀️

I am 16 year old virgin and I have been talking to this guy for about 5 months. We haven’t got the opportunity to be alone a lot but when we are he doesn’t make me feel bad about to doing certain things but he sure does try a lot. He is comming over in a few days and I have been thinking about giving him head for some time now. I don’t kno if I should or not and I honestly don’t kno hos I feel. I just don’t want to feel stupid gor doing it or regret it in the long run. Please give me some advice It would be greatly appreciated
