You don't necessarily have to have vaginal secretions in order to prove you've had an orgasm. And all I have to say is you'll know when you've had one. If your private area is warm and seems to pulse after a feeling of extreme pleasure, then you may recognize this as an orgasm. Sometimes you may cum and not orgasm, or orgasm and not cum. And who, by the way, said you didn't orgasm? I don't think anyone can say that but yourself.
