How do i ask my friend to suck my dick?

Ok so its a very long story, but basically my friend kinda made out with me a few months ago he was drunk and so was i, and we were both in relations ships so i walked away. Months later we both werent in relationships. So every now and then we would get drunk but nothing like what happend months before had happend, so i began to think he would never do it again. But one night i had gotten high with some friends and he had just got done hanging out with some of our other friends so i was gonna go hang out with my them as well but they cancelled so the friends i had smoked with just dropped me off at home, so i asked my friend if he wanted to hang out but i remembered he had a curfew so i kinda was likw nvm than. Eventually this friend calls me and asks if i just wanted to drive somewhere i had wanted to go for a while but no one ever wanted to go with me. Eventually we drove for like 30 mins, and he realized he had to go home soon so he was like i have to go home soon so imma drop you off i was like oh ok, so we get to my house and at this point we were both kinda high. So as imma bout to say bye he looks at me and is like hey can i suck your dick, at this point im kinda in shock but i also wanted to try it so after a while of hesitation i agreed, and at this point he was in shock like he never thought i would do it. So he drove down the street and well i took my dick out and he started sucking it, ( keep in mind this is the first blowjob i have ever gotten) so at this point im really nervous almost to the point of shaking so he then looks at me and asks me if i wanted to kiss and i was like sure and so we litterally made out (intensly) he eventually looks at me and asks if i would wanna suck him off at this point im down for anything so i was like yeah sure, so he gets his dick out and i start sucking his, he then looked at me and asks me if i wanted tk try something new so he got on top of md and basically rubbed his dick against mine and even came on me so at that point there was a lot going through my head and he looked at the time and realized he had to be home soon so he was like shit i have to go soon and he than looks at me and is like im so sorry dude, is it gonna be wierd between us and i was being honest and was like not ubless we make it. So we both agreed not to tell any of are other friends, and that it pretty much never happend. But now the problem is that i want to do thag stuff again but i really dont know how to come about it, cause i didnt ask last time. So i really need help
