Help on my first tattoo!

Hi, I've been learning for the past months and practicing on fruit and fake skin, today I ventured on my first ever real skin tattoo on my husband (forearm). And nerves aside, I was feeling pretty confident... until the first wipe. I had done several lines and none were taking in the ink.
I'm using a pen machine, 11RL on 6.5v (voltage at which I felt comfortable when practicing) So I stopped, adjusted to 8v and slowed my hand speed; and changed to a 9RL to go on some of the thinner lines. Things looked better. Lines looked darker and more solid. But then on some areas the needle seemed to "get stuck" on the skin! I had to pull out completely and go in again.
Now I'm full on nervous thinking I f**ed up, and feeling a bit lost about what to do next, the skin is sore so I don't want to go at the lines again. I rinse and wipe off, wrap and call it a day.
Now, how long should I wait before I can go over the lines? Should it heal completely? Thanks for any advice!

Hey, i dont know if its still needed, but for me that sounds a lot like you didn't stretch enough and/or your voltage was too low. I also practiced on fakeskin for a few months and never went above 7v. Then i did the first tattoos on myself and i had exactly the same issues as you. I was terrified of upping the voltage so the first 4 or 5 tattoos i did all all were scratchy, not taking ink. I now stretch like a motherf*****, turn the volts to AT LEAST 8.8 (i now like to line at about 9v or more, depending on the Spot and skin) and go to town. I use a cheap rotary, i think they just need more Juice to work!
