sexual dysfunction

Hello,
I think i might have a sexual disfunction. Usually the only way i ejaculate is by squizing my genitals between my legs for a couple of minutes. This is the way i masturbate since i was a kid. Now with my first sexual partner (women) i do not ejaculate during the ususal sex act. I can perform for a large amount of time (many hours) in the common position with an erect penis, penetrating - going in and out of her. Yet, i never ejaculate. And what is embarassing is that sometimes i feel the need to pee and not to ejaculate. However i am able to ejaculate in her (with condom, no plans for children) when i squeeze my genitals between my legs. Unfortunately it is rather difficult, because my penis is inside her while i squeeze my balls between my legs. Not the easiest or comfortable position. Sometimes it is fun, though. My belief is i need constant pressure and warmth rather than thrusting to get into the mood for ejaculation. However because i perform this type of sex sometimes my penis is not into her, as it is in between my legs. It is not painful for me. I have managed to ejaculate twice into her. However most of the times it is easier to ejaculate on her.
My partner does not want children, however i might, in the future, obviously with a different partner. However i am not sure that my method of ejaculating is very appropriate for this.
Any opinion would be helpful. Am also considering to consult with a medic/psychologist.
My girlfriend says it is some problem in my head. Hope not

Although about 90 percent of males masturbate by hand, about 5-10 percent masturbate by lying face down and thrusting the penis into or against the bed, pillow, or something else. Although masturbation is normal, healthy, and fun, prone masturbation causes severe sexual dysfunction in most males who practice it. This web site describes prone masturbation and the problems of its practitioners and offers case studies and approaches to becoming cured.

Although your masturbation technique is not described as prone you are suffering from the same symptoms and it's the same approach to becoming cured. A long pause from masturbation at which time you start practicing normal masturbation. The pause gives your penis time to recover sensitivity and most are not successful on first attempt.
