Cumming from a vibrator is awesome and very intense. I love the feeling of the build up right before you blow, I cum big amounts from vibrators.
Interesting. Kind of the opposite for me. I like them because they're good for going for a long time and (rather than edging in the traditional sense) just being more into the sensation of the whole act. Not just working towards cumming. It's relaxing because I can just lie there and feel stimulated. However, the orgasms I get from my vibes are more sudden and effete compared to stroking. Don't get me wrong I like that about vibes. The climax comes upon me without much buildup. Once I catch that nascent sensation that I'm going to cum, it happens quickly and my cum oozes out slowly rather than shoots out. The orgasm itself can range anywhere from almost barely there to feeling really good but, again, in a relaxing way. Not a "I need to cup my hand over my mouth" kind of climax. The stronger ones last longer than when I use my hand and feel good throughout rather than a momentary rush and subtle comedown because I can press the vibe harder into my penis while it's happening and drag it out. Basically, I cum a little bit more like how a woman cums. Which is a big reason I like them, since I'm genderqueer.
