That is:
The Male Glans Penis => The Female Glans Clitoris;
The Male Trigger Zone => The G-spot;
The Male Prostate => The Epicenter (the degenerated prostate);

To solve your problem,
1. you have to consider if you take any medications or pills;
2. test your urethral nervous response with my Finger Plier Method.
/love/fgplier.htm
You can use this method to develop a very sensitive response of the G-spot and Epicenter nerves. This method allows your man to perform a pressure stimulation massage from the vaginal orifice/G-spot deep to the Epicenter, along with the clitoral nerve.
The massage will swell the clitoris and G-spot to 3-5 times in size, as shown in

My 3-point Excitation Love Position takes the same action through intercourse.
If you fail to portrude your G-spot and engorge the Clitoris, you won't have vaginal orgasm. You should consider Heat Tea to help you out.
One more trick: The Clitoral rooting nerve is the controller of the Energy Gate (I call it the Earth Gate). The clitoral rooting nerve is located in the opposite side of the G-spot across the urethra. You must get a simultaneous stimulation on your G-spot and the clitoral base/shaft with a lot of pressure to open this energy window to allow the sexual energy trapped in the Orgasmic Pacemaker to pulse out and trigger your vaginal orgasm.
If you can not have orgasm to release the sexual energy trapped in the orgasmic pacemaker, you will experience pelvic congestion and hypertension and become anxious and aggressive.
You should try my Finger Plier Method to evaluate your sexual response first.
