premature ejaculation

At the moment i cant last more then 30 seconds to be honest
only a few strokes and im cumming.
I have purchased EMLA - would it be safe for to use without condom/ or for gf to give BJ whilst i have applied emla.

Other option is Prilligy but apparently that will only double treble the time.
I would love to last 10 mins, i dont think thats unreasnoble.

I dont think its about techniques/physiology
Joe,
You're probably holding tension somewhere in your body and don't know it. The first time I had sex(at 18) I came fast then also for my first BJ. I would cum fast even when I thought I was relaxed. I took a course with a sex/relationship coach and she helped me realize that my PC muscle was weak, I held way to much tension( so much that my prostate massager wouldn't stay in on its own). Growing up I would jerk off just to jerk off and never really enjoyed the session so I had to rewire my brain to learn to enjoy it. Pills, numbing creams don't work! I tired a numbing cream once, I came just as fast but didn't feel when I came cause I was numb! Buy some good quality lube, I like Uberlube to jerk off with. it's a silicone based lube so it doesn't dry out really fast, if you have to stop for some reason you can leave it on and it will make your skin really soft and doesn't damage clothes. Jerk off and when you're about to cum stop, take note( I mean this literally, write it in a journal or on an app on your phone) how long it took to reach that point of no return and what almost got you there. Take long deep breaths, then continue again. from 1-10 10 being busting a nut try to stop at 8-9. Try to jerk off for a longer time each time you jerk off and take note what you're feeling when you do. Don't use porn Videos or pics either. If you're having sex and your partner encourages you to cum fast tell them, like I had to do. STOP! let me enjoy this.
