Recently had a meet with someone from here and it went really poorly. I don't like how it felt and I'm looking for some outside perspective and help because I'm not sure if I did something wrong and if so I don't want to make the same mistake again.

Put up a post here recently (since deleted) looking for someone to help me out by blowing me until I cum and they swallow. No drama, no stress just a warm wet sloppy blowjob. Chatted with a few people and decided to meet one local who was interested in doing it at his place. We message back and forth for a week or so chatting about expectations, logistics, how everyone's day went and some other things.

Day of I get the address and head out freshly shaved and showered. He texts me that he's nervous and his house is a mess and I can tell he's debating pulling out of the whole thing and I tell him if he's changed his mind it's fine. I'm not pressuring him at all and it's not a big deal, I can go run some errands I need to do anyways. He wants to go through with it (his words) and when I arrive he tells me he's gonna come by and pick me up this is a "burner house nearby"?

He picks me up and drives us around the corner, and I need to be really quiet so no one hears me. We had discussed me sitting on a comfy couch or chair with my pants off, and you do your thing. I'm not gonna push his head or grab his hand he can go at his own pace with an understanding of what I was looking for. This doesn't mean I'm not gonna moan or tell him what I like but that he's free to move at his own pace for this. He puts on some porn and starts jacking himself off and asks me to do the same, which is fine I guess? After a few minuets he's gently touching me and looking at my cock but not sexually, he's looking at it like a doctor would.

15 minutes go by and he's mostly touching himself, which is fine but not really what we had talked about. We're about 30 minutes into this and his mouth has not touched my cock yet and he's really stiff and awkward and I can admit at this point I was thinking I'm not enjoying this but I'm this far, I kinda wanna cum at least which I admit is probably the wrong attitude but he's at least stroking me now.

By 45 minutes in he has used some drooled saliva to lube me and he's stroking me in a good way. I finally manage to cum and since it had been a while (not a great BJ but just a while since cum) there's a good amount and when I do he's visibly grossed out and a little upset. He wipes me down with a towel (not the swallow we discussed) and after washing out his mouth offers me a water for the ride back to my car.

This was not an enjoyable experience for me and while I'm very aware there are two of us in it I did not leave the whole thing happy. I left feeling bad about myself like I did something wrong, kinda ruined the whole day for me where I feel like it should have been the highlight of my day.

Did I do something wrong here? What can I do moving forward to not have this experience again? Looking for honest constructive criticism here so as to have better experiences in the future and moving forward.
