Blowjob talk

So I stayed at my boyfriends house last night and I gave my first blowjob...

It was so weird and honestly at first I didn’t know what I was doing but like after a while I got used to it and I wasn’t that bad. I found out that he’s a head pusher sooo 😒 literally the only reason I kind of knew what to do was just from watching porn lmao. He didn’t end up fully cumming because I got so hot under the blanket that I thought I was going to die, but like cause he loves me he told me that it was okay and that he loved it anyway and that he understands cause it was my first time. I actually want to make him cum next time so is there any tips for me cause he isn’t small so it’s kind of complicated?
