For safe pumping it's essential to use a pump with an accurate gauge. Yeah they cost more but don't fuck with your dick!
Now, stop pumping completely and let your dick heal. At least a month, possibly three. In the mean time, buy yourself a decent pump or stop pumping and use different PE methods.
Always warm-up your penis beforehand. A good five minutes with very warm towels wrapped around your penis and then 3-5 minutes of wet jelqing followed by another 5 minutes of warm towels. If you don't like towels, use a rice sock. Take a sock, fill it with rice, and microwave it for a minute. Let it cool until you can leave your finger on it if it comes out too hot. Microwave power varies so times will vary. You'll learn by trial and error. It's quick and easy and holds heat very well.
Then get a condom that fits you, NOT loose! Then roll the condom completely over your erect penis and down to the base as far as possible. Then pump to no more than 5Hg and leave it for 10 minutes. If you feel pain, STOP. Use 3HG instead. Either way, when your 10 minutes are up, out you come. Do not go over.
Then do wet jelqs and massages to get the blood flow going again for at least another 5 minutes. A hot shower afterwards is good too. The flow of hot water on the penis is good. I hope you have something other than those horrible pins-and-needles water saving torture devices they now sell as shower heads. If you don't have one, get one and take out the water restrictor. A good hot shower is one of the privileges of first world living, afaic.
Examine your penis afterwards. Look for bumps and donuting. Condom pumping helps prevent these a great deal because it helps to distribute the pressure on the penis. The condom acts as a support for the penis tissue, allowing it expand only so much.
Please go to
Thunder's Place Free PE Forums and check out Avocet's thread on pumping and the one below on condom pumping. Pretty much everyone is condom pumping now because it helps prevent damage so well. I use snugger-fit condoms precisely for this (and sadly everything else) but I am seeing gains even though I'm going slow. Because I read my ass off about pumping I haven't screwed-up yet. That's no reflection on you. It's easy to fuck it up because there's so little information about properly using a pump to PE safely.
Thunder's also has a wealth of information on what to do when you fuck-up. Do searches for threads on pumping problems, they're all over the pumper's forum. You'll learn from vets how to fix your dick.
Good luck man and please get a good pump. I got the
Deluxe Package from LA Pumps. It's a very high quality pump and while the video is a bit a goofy in a porn-trying-to-look-medical way, it actually demonstrates some good techniques. LA makes great pumps. Dr. Kaplan's is another preferred brand but I've never used it.
Let us know how it goes
