Yesterday I (19F) gave a BJ to my FwB years and he was amazed but I want to get even better

I have been having sex with my friend (19M) since we were 14. We learnt together a lot of things and he loves BJs and I dont mind giving them to him. I have problems with having sex with guys in general so ive only slept with 3 (this friend and other guys but with the others it was not very good and only a few times). With my friend is AMAZING. He has a dreamy D and is very good at sex (he has a lot of more experience than me with lot of different women). Yesterday we had sex since we stopped which was 6-7 months ago. He was actually amazed with what I did and said I got so much better (I didnt do anything with anyone else those months). I enjoy looking for new ways to make it as pleasurable as I can for him bc im a pleaser. But I tried something new with the BJ and he was shaking the whole time asking me what I was doing and that it was incredible. It made me feel so good. It was the first time I tried that and it worked out AMAZING. He actually said it was a 10/10 and that he has never experienced that before. Im happy with that but I want more. I want him to see heaven with me. I love knowing im giving them so much pleasure that they cant even move or speak. It turns me on so much. I want more. Do yall have some tricks or advice to give him that it works for yall to make men feel in paradise?
