Welcum to Pixes Problem Child!

You never said if this has always been the case. Have you ever ejaculated prematurely? Have you ever ejaculated within a perimeter you deem "normal"? The masturbation theory is a good one........and if you masterbate to ejaculation in a "normal" standard, you may have a problem with preformance anxiety. The majority of 18 year olds might just have the exact opposite of your condition in that they ejaculate too soon when in the throes of sexual excitment. Over time a person learns to know his/her own body well enough to control the way it reacts in a particular situation. At your age I suggest you see a doctor, because as pantyfanatic said, medical advice isn't within my realm. If it is a medical condition, it seems like a rather minor one and a doctor can help. If it's a psycological problem, a doctor can help with that too. Are you on any medication for something seemingly not associated? Read up on the side effects of that meds. in case it is something this simple. A change in dosage might be the diagnosis. But definitely check with your doctor first, before self diagnosing and changing any meds.

And one last thought......it might be something as simple as you needing more stimulation, either physical or visual......before and during sex. Good luck hun..........but please seek medical advice to rule out any condition that may be the inhibitor!
