Practicing on a plastic Dildo is a lot different than a real cock, right off the bat your mind is fighting off what's not working about what you're doing. My first cock sucking adventure was pretty much right in my face. I met a local guy on the old CL site, we texted for a couple of days, when the coast was clear we hooked up at his place. He laying naked on his bed, with me right next to him. He said" I could do anything I wanted too," looking down at his soft cock just laying there, I went down on him; for me it was great! Texture was a little rubbery, but once it began to grow stiffer I was able to get into it more. Deep-throating his cock didn't seem to be an issue, I'd say his cock was about 8" great head and shaft. After a bit I told him when he was ready to cum, just cum don't tell me he was going to. When the time was right, he did, the whole experience was awesome! Not every guy you meet will be like the first, just keep that in mind, we all have our different quirks.
