So I gave my girlfriend a clitoral orgasm from going down on her once. The next time when we were having sex she told me she felt one she had never experienced before. She explained that the clitoral one tends to be sharp and fast but the second one was dulled but prolonged and it happened inside rather than out. Was that a g-spot stimulation or something else? She thinks it might have been... but to me it didn't seem like she was in absolute ecstacy, as I imagine stimulating the g-spot would. She just looked entirely content with herself.
