Here is what I did to fight my premature ejaculation problem.
At first, I tried using all sort of products, namely a benzocain gel, stud100 (I think that’s the name) which is a spray, and china brush.
The gel and the stud 100 had to be applied 5-10 minutes prior to sexual intercourse, and were supposed to last for around 15 minutes. I never had much success with those. Then came China Brush. You have to apply it at least 30 minutes before having sex, but it lasts much longer. There are different versions of it sold. The most popular is a small box with the face of a chinese man on it. It should last you for awhile, even though the box will seem tiny to you.
Anyway, I recently started applying it every night, even on the days where I don’t see my girlfriend. This caused my penis to be much less sensitive, even on the following morning. My premature ejaculation problem was weird though, sometimes even when numbed by China Brush I’d cum quickly, in like 1 minute when I was on top, other times I wouldn’t use it and I had no problem lasting for awhile. However, my awesome discovery is cock rings. I started using a robber cock ring a few days ago when having sex, and OMG, it’s incredible. At first, I’d apply china brush, and have sex with the GF about 30-45 minutes after that, using a cock ring, and the sex was incredible. I could still feel her, I remained rock hard and I had PERFECT control over my ejaculation. It was better than the few times where I used viagra with a completly numbed penis from a benzocain gel. Not only that, but the cock ring will add maybe .2” EG, which is nice. Anyway, fastforward a few days, I went to see 40 years old virgin with my girlfriend, and for some reason she was REALLY horny, she pulled my cock out in the theater and she was playing with it :D I was kinda nervous, because I had no china brush on me and it had been a few days since I last used it, and I knew she’d jump on me as soon as we’d be home. Long story short, on the days where I’m nervous about premature ejaculation, I usually cum quickly. Needless to say, I was damn surprised when I started fucking her hard, with perfect control. Cock rings never failed me yet, which is a big confidence boost, because I think less and less about premature ejaculation. I think it’s mostly a mental thing, so finally being able to have sex without worrying about it is nice.
