Solution for delayed ejaculation

I had sex with my girl friend .i cant reach orgasm as it takes longer duration.after 30 min ejaculated.i tried masturbating many times but i cant reach orgasm.wat to do?

You message isn't clear.  Are you saying you can't reach orgasm having sex with your girlfriend at all, or it takes 30 minutes?  Can you have an orgasm when you masturbate, and if so, how long does it take?

Some more questions:

How old are you?

Is this the first women you've had sex with, and if so did you have similar problems before?

Are you taking any medications or recreational drugs?

and how many times have you had sex with your current girlfriend?

If you are circumcised it can cause a loss of sensation (due to loss of nerves and exposure of the glans) that lead difficulty reaching orgasm. Some men have found that foreskin restoration has helped.
