Interesting Thread!
I am a lucky one I suppose as I have both clitoral and vaginal. Clitoral, generally speaking, only happens with hubby. Primarily because (I think) hi hits all the right places with just the right pressure to bring one on. My Bull just doesn't have the technique down, but he does try and it does feel wonderful, but it just doesn't happen.
I can also obtain vaginal orgasms with both hubby and my Bull. So don't think for a moment that my husband is somehow 'lacking' - by far, if counted (both vaginal and clitoral) I have had many more orgasms with him than I've had from black cocks.
The difference (to me) is that clitoral orgasms are like intense electric shocks running through me, almost as though I'm hooked up to a wall socket! They are intense and shoot throughout my body, again, like an electric current. Vaginal orgasms are much more deeper, enveloping me in waves of warmth, feeling muscles, both deep inside me and more exterior muscles in the legs and pelvis contracting and releasing. I've seen videos where the woman is literally shaking from an orgasm, well, that's not me. The are more contract, relax, contract, relax accompanied by the warmth I spoke of, kind like a warm blanket.
All that being said, I am NOT a multi-orgasmic kind of girl! For example, if my bull is having me and I have an orgasm, I'm pretty much done until I'm able to relax for a while and he starts again. Then the process resumes. So, if he has me three separate times in an evening, I consider myself very lucky if I achieve two orgasms. This isn't to say that he doesn't leave me satisfied! Far from it. My orgasms are largely my responsibility and although he's really trying, it's either going to happen, or not. It is never (in this instance) his fault.
That's me, but remember two very important things. Every woman experiences orgasms differently. What I experience may not be experienced by others. Also, sexual enjoyment comes primarily from one place - the woman's brain! So the setting has to be right, the mental images have to be right, and the stimulation itself has to be right, or it aint gonna happen.
Hope this helps!
