Can testerone help?

I am a 23-year-old woman, and have been sexually active since I was 15. I started masturbating when I was 8 years old using my fingers on the right-side of my clitoris. I have used the same technique until I was old enough to purchase my own vibrator. Unfortunately, I am not able to feel any pleasure when engaging in intercourse with my spouse unless his penis hits my g-spot (meaning no orgasms). I get extremely aroused, to the point of humping a chair lol, but any stimulation other than a vibrator to the side of my clitoris results in absolutely nothing...

I can feel his penis or the object that I am using in my vagina, but no pleasure is derived from my efforts. Plain and simple, only certain vibrators with clitoral stimulation came make me orgasm.

Now I was reading in one of these forums that a woman went to her doctor and was prescribed testerone to apply directly to her clitoris, which she claimed worked. Has this treatment been known to work?

Please do not tell me to relax or try oral, as I already have. Only the people who are experiencing these symptoms can truly understand the frustration.
